I have a stasis ulcer on my leg. the infection is gone, but it still itches. how can i stop the itching?

Lotio / Benadryl (diphenhydramine) : Itching is very common and is a consequence of the inflammation from the healing ulcer and any associated venous insufficiency. Lotion and/or Benadryl (diphenhydramine) ointment could help. Compression always helps keep the venous insufficiency in check an may keep the itching at bay.

Swelling?: If there is swelling associated with the ulcer then the swelling needs to be treated. Sometimes the skin is dry and also needs to be moisturized. If there is redness and itching then it could be a fungal infection as well. Pleas seek the opinion of your vascular surgeon.

Reduce inflammation: Even though your infection is gone, there is still inflammation and that is what itches. Compression is helpful. A mild steroid cream can also help. Bottom line, though, is that the underlying venous insufficiency that caused the inflammation and ulceration in the first place, needs to be treated.

Swelling: When you have venous insufficiency there will always be some swelling. If there is swelling and the skin stretches it will crack. You may never see the cracks in the skin but they will itch. Try to moisturize your legs twice a day and increase the compression on your legs. Moisturizing the skin will make it less likely to crack.

Moisturize: Stasis ulcers are primarily a result of venous insufficiency which causes inflammation. Controlling the edema is your primary concern. This is done by limiting salt intake, elevation of legs while at rest and compression while walking. Keep the skin moisturized well. If itching persists consult a dermatologist for an appropriate steroid cream.
