Talk to Dermatologist on Foot Nail Problem

I had an ingrown nail on one side, which caused a wound. Later, whole nail got affected and got off own its own gradually. Then new nail formed which was not fully grown to its length but has now again ingrown to one side. Its ver difficult and painful to cut because as aforementioned, its not grown to its length properly. And one important thing, nail is advancing forward from side inside flesh, causing pain and wound.
