Dear Doctor, I had a skin transplant from my thigh and placed on my right foot because I had met with an accident long back. While part was recovered long back. But only some 1sq.cm area of the wound/skin transplant never recovered fully. The black color scab is always present. I have tried once to peel off then it formed again. But new skin has never formed back. After many days I have again today peeled off some part of the scab due to frustration. How to get back the skin? Thank you.
