Huge insect bite reaction on leg, what to do?

This is my leg, not Ds’s — I got bitten 2 nights ago, not sure what by, and my thigh has swollen up — the bits is red and very big, with a hard area of reddish skin about 6 inches across all around it.
I’m not in pain, it just itches and I’ve been using eurax hydrocortisone which helps a bit, but should I be doing anything else to get rid/help fight whatever it’s reacting to?

Sorry BITE not bits!

It should have gone down by morning — cold compresses will take the heat out of it and if you have any anti-histamine tablets, take one. That will stop your body’s reaction.

Tis a bugger I know, a mozzie got me the other day!

Thankyou WMMC

As long as it’s normale to be so huge..

Haven’t any piriton etc so will just try the ice.
And try not to scratch!

Anti histamine tablets and anti histamine cream.

Sounds a nasty one!

Have got just the same on my leg, after a bite last night — am using anti-hist and hoping for the best, as am on show this weekend

Hi! So many people get this every summer — DH had one on his ankle last year and it was huge. Have you tried an antiinflammatory? like ibuprofen?

A good port of call would be a local pharmacist who can suggest ways of reducing swelling and guide you as to medication (depending if you’re on other meds/pregnant/breastfeeding)

or even better if you can get to see your GP as you may need anti-biotics as these bites can lead to infection/cellulitis which can be very nasty

Hope it’s better soon x

Oh no, it’s a good thing — it shows your immune system is very efficient. The only time you need to worry is if you have breathing difficulties or your veins start to track from the centre of the bite (this can indicate blood poisoning).


Swollen Legs: Causes and Treatment

Articles On Swelling in Legs

Swelling in Legs

Swelling in Legs — Swollen Legs: Causes and Treatment

Have you noticed lately that your socks are tight and your pants feel snug? Your legs swell for two main reasons:

  • Fluid buildup (edema): It happens when the tissues or blood vessels in your legs hold more fluid than they should. This can happen if you simply spend a long day on your feet or sit for too long. But it may also be a sign that you’re overweight or don’t get enough exercise, or of more serious medical conditions.
  • Inflammation: It happens when the tissues in your legs get irritated and swollen. It’s a natural response if you break a bone or tear a tendon or ligament, but it also may be a sign of a more serious inflammatory illness, like arthritis.

Things That Cause Fluid Buildup

Several things can lead to extra fluid, or edema, in one leg, or both:

Congestive heart failure: This happens when your heart is too weak to pump all the blood your body needs. It leads to fluid buildup, especially in your legs. Other symptoms of congestive heart failure:

Vein Issues

Deep vein thrombosis (DVT) and thrombophlebitis: If you haveВ DVT, it means there’s aВ blood clotВ in a vein in your leg. It could break off and travel to yourВ lung. When that happens, it’s called aВ pulmonary embolism, and it can be life-threatening.

InВ thrombophlebitis, also called superficial thrombophlebitis, clots form closer to the surface of theВ skinВ and aren’t likely to break off.

One of the firstВ symptoms of DVTВ or thrombophlebitis is one swollen leg (especially the calf), as blood pools in the area. Check with your doctor right away if you have swelling in one leg or any of these other symptoms:

  • Leg pain, tenderness, or cramping
  • Skin that’s tinged red or blue
  • Skin that feels warm

Varicose veins and chronic venous insufficiency: You get these conditions when the valves inside your leg veins don’t keep the blood flowing up toward your heart. Instead, it backs up and collects in pools, causing bluish clusters of varicose veins on your skin. Sometimes, they can make your legs swell.

Some other symptoms might include:

  • Pain after sitting or standing for a long time
  • Changes in skin color — you might see clumps of red or purple veins, or the skin on your lower legs might look brown
  • Dry, irritated, cracked skin
  • Sores
  • Achy legs


Kidney Problems

Long-term kidney disease happens when your kidneys don’t work the way they should. Instead of filtering water and waste material from your blood, fluid gathers in your body, which causes swelling in your arms and legs.

You may also notice symptoms like these:

Acute kidney failure — when your kidneys suddenly stop working — can also cause swollen legs, ankles, and feet. But it usually happens when you’re hospitalized with other problems. Learn more about acute kidney failure symptoms and causes.


Sometimes, swelling can be an unwelcome side effect of prescription drugs. The medications most likely to cause swollen legs include:

  • Heart medicines called calcium channel blockers are often to blame:
    • Amlodipine (Norvasc)
    • Nifedipine (Adalat CC, Afeditab CR, Nifediac CC, Nifedical XL, Procardia)
  • Nonsteroidal anti-inflammatory drugs (NSAIDs), like:
    • Aspirin
    • Ibuprofen
    • Naproxen
    • Celecoxib (Celebrex)
  • Certain diabetes drugs, including metformin
  • Hormone medications containing estrogen or progesterone
  • Some antidepressants

Call your doctor if you take any of these drugs and get swollen lower limbs. Learn more about common medication side effects.


By the third trimester, your growing baby puts pressure on the veins in your legs. This slows the circulation of your blood and causes fluid to build up. The result: mild swelling.

If you notice these other symptoms as well, let your doctor know because it might mean you have a serious condition called preeclampsia:

  • Severe swelling, especially around your eyes
  • Bad headache
  • Vision changes, like blurriness or sensitivity to light

If, during the last trimester or soon after delivery, you have swollen legs and shortness of breath, talk to your doctor about a condition called peripartum cardiomyopathy, a type of heart failure related to pregnancy. Learn more about swelling and other discomforts during pregnancy.

Things That Cause Inflammation

If fluid buildup isn’t to blame for your swollen legs, it could be inflammation. Common causes include:

Arthritis and Other Joint Problems

Several diseases and conditions can make your legs swell:

  • Gout: A sudden painful attack caused by uric acid crystals in your joints that usually follows drinking heavily or eating rich foods. Learn more about the symptoms of gout.
  • Knee bursitis: Inflammation in a bursa, a fluid-filled sac that acts as a cushion between bone and muscle, skin, or tendon. Learn how to treat knee bursitis.
  • Osteoarthritis: The wear and tear type that erodes cartilage. Learn more about osteoarthritis symptoms.
  • Rheumatoid arthritis: A disease where your immune system attacks tissues in your joints. Learn more about rheumatoid arthritis.


Injuries — Strains, Sprains, and Broken Bones

If you twist your ankle or break a bone, you’ll likely get some swelling. It’s your body’s natural reaction to the injury. It moves fluid and white blood cells into the area and releases chemicals that help you heal.

Some of the most common injuries are:

Achilles tendon rupture: This is your body’s largest tendon. It connects your calf muscles to your heel bone. It’s what helps you walk, run, and jump. If it tears, you might hear a pop then feel a sharp pain in the back of your ankle and lower leg. You probably won’t be able to walk. Learn more about Achilles tendon injuries.

Anterior cruciate ligament (ACL) tear: Your ACL runs diagonally across the front of your knee and holds the bones of your lower leg in place. When it tears, you’ll hear a pop and your knee may give out. It’ll also be painful and swollen. Learn more about ACL injuries.

Cellulitis: This serious infection happens when bacteria like streptococcus and staphylococcus get in through a crack in your skin. It’s most common in your lower leg. Other symptoms include:

  • A red area of skin that gets bigger
  • Tenderness
  • Pain
  • Warmth
  • Fever
  • Red spots
  • Blisters
  • Dimpled skin

Cellulitis can spread through your body quickly. Go to the ER if you have:

  • A fever
  • A red, swollen, tender rash that changes rapidly

See your doctor as soon as you can (the same day is best) if you have:

  • A swollen, red, tender, expanding rash but no fever.

Infection or wound: Anytime you get a cut, scrape, or more serious wound, your body rushes fluid and white blood cells to the area. That causes swelling. If it lasts longer than 2-3 weeks, see a doctor.

If the wound gets infected, you could have more swelling. Swelling is normal for a few days. It should peak around day 2 and start to improve. If you have diabetes or another condition that affects your immune system, see your doctor. Learn more about the signs of a skin infection.


What Should I Do About My Swollen Legs?

You can try these home remedies to ease the swelling:

  • Cut back on salty foods.
  • Wear compression stockings.
  • Get exercise every day.
  • On long car rides, switch positions and stop for breaks as often as you can.
  • When you fly, get up from your seat and move around as much as possible.
  • Raise your legs above your heart level for half an hour, several times a day.

But since leg swelling can be a sign of something serious, don’t ignore it. If you notice other symptoms, especially leg pain, shortness of breath, or extreme fatigue, call your doctor right away.

How to Take Care of a Dog’s Swollen Leg

When your leg is injured, you can easily tell friends, family, or medical personnel what happened, how the injury feels, how much pain you are in, and whether or not you need emergency assistance. However, when your dog’s leg is injured, he can’t really tell you much of anything other than showing signs of being in pain. That can be a problem because if you don’t know what happened, it can be hard to take care of the problem yourself. Based on signs and symptoms, though, you can usually at least determine if your pup needs emergency medical attention or if a wait-and-see attitude might be preferable.

Evaluate the dog’s injury

There are a lot of things that may result in your dog’s leg being swollen. Snake bites, sprains, breaks, abscesses, cancer, and more can all result in swelling. That’s why the first thing you need to do is evaluate the swelling. Has it been slowly swelling up over a few weeks? If so, you should probably take your pooch to the vet to discover the underlying cause, which could be an abscess, arthritis, or a tumor, among other things.

If the leg wasn’t swollen one day and is the next, then you need to look at the leg to see if you can figure out what happened. See if there are any puncture marks or bloody wounds or if it seems like the bone isn’t laying straight. If you notice anything drastic like this during your visual inspection, take your dog to the vet.

Next, manipulate the joints on the leg, starting with the toes and working all the way up to the hip joint. Use the dog’s opposite, unswollen leg as a baseline to compare the normal range of movement against that of the injured leg. If you notice any loud pops or cracks, or if the dog seems to be in extreme pain, take her to the vet. If the leg seems a little stiff or doesn’t have any movement problems, you may wait overnight to see if the swelling and pain goes down.

If the swollen area feels spongy and stays indented after you touch it, take your dog to a veterinary hospital immediately. This is called pitting edema, which can be a sign of life-threatening vascular or lymphatic disease, according to MedicineNet.

When dog leg injuries are particularly painful, especially if the pup won’t let you closely examine her leg, take her to the vet. VCA Hospitals says that examining certain injuries yourself could result in further injury to your dog, even if she doesn’t struggle. Your vet can offer pain medications or even sedate her in order to perform a thorough investigation of the injury, which may require diagnostic tools such as an X-ray.

Dog leg injuries you witness

Of course, if you saw the reason for the swelling, you have a head start because you likely already know the cause. Animal bites that result in swelling require a trip to the vet sooner rather than later, especially if it was a potentially rabid animal or a snake.

If he fell down while you were playing, the injury might be a sprained joint or broken bone. If he appears to be in a lot of pain, particularly if he yelps when he tries to put weight on it or when you try to examine it, a vet visit is in order. Otherwise, you may wait a day to see if the swelling goes down, which it will if your dog sprained his ankle. If it does not go down and the pain does not seem to be going away, take him to the vet.

Caring for the swelling

If you wait before taking your dog to the veterinarian, you will need to care for the swelling in the meantime. A cold compress can reduce swelling and help numb mild pain. PetMD also suggests soaking the injury in an Epsom salt bath. It is important to make your dog relax and move the injured leg as little as possible. Crating your dog can help with this. You can give your dog a pet-safe nonsteroidal anti-inflammatory drug, or NSAID, but call your vet first to make sure you give her one that is safe for dogs because many over-the-counter NSAIDs made for humans are toxic to dogs, according to WebMD.

What do you mean by swollen legs?

There are a surprising number of different kinds of swelling of the legs. One leg or both legs could be swollen. If both legs, it could be symmetrical or worse on one side. A specific part of the leg(s) could be swollen, or the entire leg(s). It could have come on suddenly or gradually. It could be there all the time, or it could come and go. It could be painful nor not. Taking into account all these things will help narrow down the likely cause.

What are lipoedema and lymphoedema?

Where could the swelling be coming from?

Most often the swelling comes from fluid in the spaces between the cells in the legs. When this is the case it is called oedema. It is called pitting oedema if a dent made when you press with your fingertip stays in the skin after you have taken the fingertip away.

Peripheral oedema

The swelling could also be coming from skin, bones, tendons — really from any tissue of the leg.

What are the causes of swelling of both legs?

The most common cause of swelling in both legs is oedema. This is a collection of fluid in between the cells, which are the building blocks of the tissues of our body. Oedema can occur in one particular part of the body, or it can be generalised. If generalised, gravity takes the fluid to the part of you which is hanging down, or ‘dependent’. This type may be called ‘dependent oedema’ by a healthcare professional. For most people, this oedema affects their legs and tends to improve overnight after you have had your legs up. See the separate leaflet called Oedema (Swelling).

If both legs are swollen to the same level, this is likely to be oedema. Causes of oedema affecting both legs symmetrically include:

  • Heat. Some people will find their legs swell up a little in hot weather. Usually this is nothing to worry about and does not need treatment.
  • Long journeys or being immobile for other reasons. If your legs are hanging down and not moving for long periods of time, you can develop swollen legs. This improves once you are walking about again, or once you lie down at night. This happens because your muscles are not working to move the blood in your blood vessels around. This means the blood pools in the bits of you which are hanging down, putting pressure on the blood vessels and forcing fluid out into the spaces between them. To avoid this, get up and walk around regularly if possible. If not, move your feet and legs around as much as you can.
  • Pregnancy. Pregnant women may have swollen legs in late pregnancy. Usually this is par for the course and nothing to worry about, but if you are pregnant, your midwife will be doing regular checks to be sure you don’t have a blood pressure problem (pre-eclampsia) causing it.
  • Heart failure. If you have this condition, your heart is not working as effectively to push the blood around your circulation. You may also feel out of breath, and this can be worse when lying down flat at night or on walking.
  • Anaemia. This is a problem with the red blood cells of your body.
  • Kidney diseases such as nephrotic syndrome, acute kidney injury and chronic kidney disease.
  • Conditions where there are low levels of protein. If there are low levels of protein in the blood, less fluid is drawn into the blood from the surrounding areas. Conditions causing low protein levels include malnutrition, nephrotic syndrome, liver failure, and a gut condition called protein-losing enteropathy.
  • Side-effects of medicines such as calcium-channel blockers.
  • Having very low thyroid levels (hypothyroidism). This is normally accompanied by other symptoms such as tiredness and gaining weight.
  • Idiopathic oedema. This means there is oedema but no specific cause has been found for it.

What are the causes of swelling affecting one leg or part of one leg?

There are numerous causes including:

  • Injuries — for example, fractures, sprains, large bruises.
  • Wear and tear arthritis (osteoarthritis) — in particular this might affect a knee (or both knees) or the big toe(s).
  • Joint problems caused by inflammation — for example, gout, rheumatoid arthritis, psoriatic arthritis. One or more joints would be warm, red and painful.
  • Skin infections — for example collections of pus (abscesses) or cellulitis.
  • Skin reactions — for example an allergy to a bite or sting or medicine.
  • Deep vein thrombosis (DVT). This is a blood clot in the deep blood vessels, which most commonly affects the calf. You are more at risk of a DVT if you have recently had a period of time when you didn’t move very much. Examples include a long plane journey, an illness, an operation. If you have cancer or are having treatment for cancer, your risk is also increased.
  • Bone infection (osteomyelitis).
  • Lymphoedema. In this condition lymph fluid collects in the tissues because it can’t drain very well. This is usually because the lymph nodes are blocked for some reason. This can happen after an operation, after radiotherapy, or due to cancer, injury or infection.
  • Baker’s cyst. This is a soft swelling at the back of your knee.

What are the symptoms of swollen legs?

Having ‘swollen legs’ is a symptom itself, but legs can be swollen in different ways. The clue to the cause (and therefore the treatment) may well be in the type of swelling. The swelling can be:

  • One-sided or both-sided. Oedema due to conditions of general body systems is usually on both sides and is symmetrical (for example, if due to heart failure or pregnancy or kidney problems.) One-sided swelling is more likely to be due to a problem with a particular part of that leg.
  • In a specific area or generalised. Swelling around joints is usually caused by injury or a type of arthritis. Swelling in specific areas of skin may be caused by allergy or infection. Swelling around the back of the heel suggests a problem of the Achilles tendon, etc. Generalised swelling, especially if on both sides, is likely to be oedema.
  • Painful or painless. Painful conditions include infections, deep vein thrombosis (DVT), injuries and joint problems. Oedema is not usually painful, although legs can ache and feel tight.
  • Accompanied by red (inflamed) or normal skin colour. If the skin is reddened, it is likely to be due to an infection (such as cellulitis), or inflammation (for example, gout, rheumatoid arthritis or DVT).
  • Pitting or not. Pitting means that if you press a fingertip into the swollen area and then take your fingertip away, a dent remains in the skin. (See photo earlier in leaflet.) Oedema tends to be pitting. Lymphoedema, a condition where there is a blockage to lymph fluid, does not usually pit so much.

Are there any other symptoms?

In addition to the leg or legs being swollen, there may be other associated symptoms. Again, these help give a clue to the cause of the leg swelling. For example:

  • Breathlessness which started at the same time as the leg swelling might suggest heart failure (if both legs) or DVT (if one leg) spreading to the lungs (pulmonary embolism).
  • A high temperature (fever) suggests some type of infection.
  • Tiredness might suggest a more general illness, such as anaemia or kidney problems.
  • Diarrhoea might suggest a gut problem affecting the amount of protein being absorbed in the guts.
  • Being yellow (jaundiced) suggests a liver problem, such as cirrhosis.
  • Swelling in other places other than the legs — for example, in the tummy, hands or around the eyes. This would suggest a problem with another or a general body system rather than a problem with the leg or legs.

Do I need to see a doctor?

If you don’t know why you have swollen legs, or you know the reason but it isn’t settling then see your doctor. There are so very many causes for swollen legs that it is important to make sure it isn’t due to something which needs treatment.

If your legs swell up a little in the hot weather but go down again overnight, you don’t need to see a doctor. Or if both ankles are a little puffy after a long flight but there is no pain or redness of the calf, and the puffiness settles quickly then you do not need to see a doctor. Minor swellings from bites or trivial injuries don’t usually need medical attention. In most other situations, it is wise to consult a health professional. If you have swollen legs and are pregnant, make sure you keep your regular appointment with your midwife. Your midwife will regularly check your blood pressure, and check your wee (urine) for protein to make sure your swollen ankles are not a sign of anything serious.

When should I see a doctor urgently?

In some situations, the cause of swollen legs can be serious, and you should see a doctor as an emergency. Obviously if you have had a serious injury and think you have a broken leg, you would attend an accident and emergency (A&E) department.

You should see your GP urgently if you:

  • Think you might have a deep vein thrombosis (DVT). This might be the case if one calf is warm, swollen, red and tender. You might have swelling in the foot of that leg. A DVT is more likely if you are not very active — due to being in a wheelchair, for example, or after an operation or illness. It is also slightly more likely if you have recently been on a long flight.
  • Feel out of breath.
  • Have a high temperature.
  • Feel generally unwell in yourself.
  • Are in severe pain.
  • Notice your skin has turned a yellow colour.

What will the doctor do?

Your doctor will want more information about the swelling in your leg(s). For example, when it started, if it hurts and whether it comes and goes or stays much the same. They will also want to know if you have been on any recent long journeys or had any times when you were not very mobile recently, and if you are on any medicines.

The doctor will examine your legs and then may go on to examine other areas. This might include your chest and/or tummy and groins.

Will I have to have any tests?

This will depend on the information the doctor has obtained by listening to you and examining you. In some cases, no further tests will be needed. In others, tests will be advised. These might include:

  • Testing your urine. This can usually be done in the doctor’s surgery. The urine is tested with a dipstick to see if there is any protein in it, which might suggest a kidney problem, for example.
  • Blood tests. You might have blood tests to check you for anaemia, heart failure or a DVT. Tests may be done to check the function of your kidney,liver or thyroid gland.
  • A chest X-ray. This would check you for conditions such as heart failure or a pulmonary embolism.
  • An ultrasound scan of the leg. This can look at the nature of the swelling and establish where it is coming from. It can be helpful to diagnose tendon problems (such as Achilles tendinopathy), DVT and other problems in the veins of the legs.
  • An X-ray if a fracture or infection of the bone is suspected.

Depending on the results of these tests, other investigations may be needed in some cases.

What is the treatment for swollen legs?

Treatment will be different depending on the cause. If the cause is fluid in the legs (oedema), this can often be relieved in the short term by taking tablets called ‘water tablets’ (diuretics). Diuretics increase the amount of fluid that the kidney filters off to be passed in your wee (urine). So when you take diuretics you eventually pee away some of the fluid which was collecting around your legs.

However, diuretics are not used for many causes of swollen legs. A few examples of some treatments of some common causes are as follows.

  • DVT is treated with medicines to thin the blood and break up the blood clot.
  • Heart failure is usually treated with a number of medications to improve your heart function, including diuretic medicines.
  • Skin infections (cellulitis) or bone infections (osteomyelitis) are treated with antibiotics
  • Where the cause is a medicine, that medicine can usually be changed, or stopped, or the dose reduced.

Are there any complications?

Again this depends on the cause. The most common complication in swollen tissue is infection. Where the skin is stretched, it is more prone to be dry. If it is dry, it is more prone to breaks in the skin, allowing germs from the outside of the skin underneath. This can result in cellulitis of the legs. If this is the case a large area of the skin of the legs becomes hot and red. It may cause a high temperature (fever).
