I do this till my fingers are red raw, not just around the nail, I peel skin from all around the thumb that I have scars. Its just a thing I do when either I'm bored or nervous. You can see when I'm happy and relaxed and nothing is stressing me out because I dont have plasters round my thumbs :-) But when the skin does grow back it does feel tight, I went to docs and he gave me some cream but had to wear stupid finger bandages. I now just try and control it myself and use hand cream so I dont end up picking at the dry skin.
