I have a spot on the back side of my shoulder about the size of a ping pong ball. It is small. It does not hurt or anything. Nor has it. It looks like my skin is peeling just in that little area. I have had it for a while I think well over 6 months and I have had no problems with it really. I have not had a sunburn in a couple of years. I am perfectly healthy I dont feel sick or have. I dont do drugs. it does not look disgusting or anything. I am curious what it would be. I hope I described it good enough. I have a picture if any one wants to see. http://i252.photobucket.com/albums/hh7/djskype/Picture19.jpg http://i252.photobucket.com/albums/hh7/djskype/Picture18.jpg
