What should you know about venous stasis rash?

When blood does not move efficiently back up from the legs, fluid can collect around the ankles and lower shins. The skin may become itchy, dry, scaly, reddish-brown, or thickened. Small cracks can develop, and scratching can damage the protective surface. The rash is different from conditions such as [Atopic Dermatitis](/conditions/atopic-dermatitis/), [Contact Dermatitis](/conditions/contact-dermatitis/), [Psoriasis](/conditions/psoriasis/), or [Ringworm](/conditions/ringworm/), so examination matters when the cause is unclear.

Arrange a medical review to assess swelling, pulses, skin condition, and possible vein problems. Use a bland moisturiser on intact skin, wash gently, avoid hot water and scratching, and keep the legs moving with comfortable walking if suitable for you. Elevation may ease swelling. Compression garments can help some people but should be recommended after circulation has been checked; do not start them over an open or infected area without advice. Look at the skin regularly for cracks or sores.

Seek urgent help for sudden one-sided leg swelling, marked pain, warmth, or breathlessness. Prompt review is needed for a spreading red area, pus, fever, a rapidly worsening sore, or skin that turns very dark. A persistent ulcer near the ankle also needs professional care because healing may be delayed when venous pressure remains high.

Ask what is driving the swelling, whether your circulation should be tested, which compression level is suitable, and how to dress any sore. Ask which moisturisers or steroid treatments are appropriate for your skin and how often the area should be checked.
