My mother is having skin problem on her heel for past 2 years. It does not pain normally. But it itches. Also if any cut occurs at the problem area, it pains. Tried treatment earlier also, but it didnt cured. Recently i moved to Mumbai, so I think there are good doctors here and chances for the right treatment are high. Most of the dermatologist I saw here are mainly doing anti aging things or cosmetic surgeries. Can you recommend a good doctor for this thing without the need of any surgery ? Pics of the affected area are attached.
