I was in a bad accident 5 years ago, and part of my injuries was a badly disfigured, indented patch on my leg which had a skin graft. The indent is very pronounced, and it looks like i have a section of my leg missing on one side. I also have severe nerve damage to this area. Is it possible to have cosmetic surgery to "fill in" this very large indent? If so, is it done on the NHS or do you have to go private?
