Venous leg ulcers are open, often painful, sores in the skin that take more than 2 weeks to heal. They usually develop on the inside of the leg, between the knee and the ankle.

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

• swollen ankles (oedema)
• discolouration or darkening of the skin around the ulcer
• hardened skin around the ulcer, which may make your leg feel hard
• a heavy feeling in your legs
• aching or swelling in your legs
• flaky, scaly and itchy skin on your legs (varicose eczema)
• swollen and enlarged veins on your legs (varicose veins)

A venous leg ulcer can be susceptible to bacterial infection.

Symptoms of an infected leg ulcer can include:

• worsening pain
• a green or unpleasant discharge coming from the ulcer – redness may be harder to see on black or brown skin
• redness and swelling of the skin around the ulcer
• a high temperature (fever)
• an unpleasant smell coming from the ulcer

Contact your GP if you think you have developed a venous leg ulcer. These are unlikely to get better on their own, as they usually require specialist medical treatment.

You should contact your GP or leg ulcer specialist as soon as possible if you have been diagnosed with a venous leg ulcer and have signs of an infection.
