Venous leg ulcer

A leg ulcer is a long-lasting (chronic) sore that takes more than 4 to 6 weeks to heal. They usually develop on the inside of the leg, just above the ankle.

The symptoms of a venous leg ulcer include pain, itching and swelling in the affected leg. There may also be discoloured or hardened skin around the ulcer, and the sore may produce a foul-smelling discharge.

See your GP if you think you have a leg ulcer, as it will need specialist treatment to help it heal.

Your GP will examine your leg and may carry out additional tests to rule out other conditions.

Symptoms

Venous leg ulcers are open, often painful, sores in the skin that take more than a month to heal. They usually develop on the inside of the leg, just above the ankle.

If you have a venous leg ulcer, you may also have:

swollen ankles (oedema) discolouration and darkening of the skin around the ulcer hardened skin around the ulcer, which may make your leg feel hard or even resemble the shape of an upside-down champagne bottle a heavy feeling in your legs aching or swelling in your legs red, flaky, scaly and itchy skin on your legs (varicose eczema) swollen and enlarged veins on your legs (varicose veins) an unpleasant and foul-smelling discharge from the ulcer


Swelling in the legs and ankles

Venous leg ulcers are often accompanied by swelling of your feet and ankles (oedema), which is caused by fluid. This can be controlled by compression bandages.

Keeping your leg elevated whenever possible, ideally with your toes at the same level as your eyes, will also help ease swelling. You should put a suitcase, sofa cushion or foam wedge under the bottom of your mattress, to help keep your legs raised while you sleep.

You should also keep as active as possible and aim to continue with your normal activities. Regular exercise, such as a daily walk, will help reduce leg swelling. However, you should avoid standing or sitting still with your feet down. You should elevate your feet at least every hour.

Itchy skin

Some people with venous leg ulcers develop rashes with scaly and itchy skin.

This is often due to varicose eczema, which can be treated with a moisturiser (emollient) and occasionally a mild corticosteroid cream or ointment. In rare cases, you may need to be referred to a dermatologist (skin specialist) for treatment.

Itchy skin can also sometimes be caused by an allergic reaction to the dressings or creams applied by your nurse. If this happens, you may need to be tested for allergies.

It’s important to avoid scratching your legs if they feel itchy, because this damages the skin and may lead to further ulcers.
