Hello, this is my first post, I'm 15. When I was 3 or 4 I got an electric shock which burned my fingers, I got a small skin graft on the top of my middle finger and a smaller one on the finger next to my pinky finger, it was either that or amputation- god forbid, my parents had to get a loan. The bigger one is darker colored, the skin for it was taken from the side of the same hand, and the wrist, it's not very noticeable.

My question is, do skin grafts last FOREVER, will they last forever and grow as my hand grows, do they become like ordinary skin because I can feel with them normally. The bigger one was very deep an burned to near the bone, I remember the doctor saying that, but now I'm fine, well, it's long forgotten now, it's been 11 years, I have never visited a doctor with regards to them, after that I remember putting some cream and putting my hand in salt water, then I went to the doctor once and it was over, the whole thing was long forgotten, I didn't even know what a skin graft was until recently and I'm just wondering, should I be worried or do skin grafts just become a normal part of your skin, because I remember that when I was small the grafts were bulging a bit but now they aren't much, so do they last forever, is it over or is there something in the longterm that I have to do or something?
