I turned 29 in Jan. but have decided to stay 28 for a while longer (God owes me a couple of months;)) A skin graft isn't the worst thing because the amount of skin they would take for your shoulder would be extremely small. The area they take the skin from hurts way more than the area they put it on.
Good luck with Dr.Elhassen! (Funny thing, my mom thought his name was pronounced Eel-hausen so she thought he was going to be swedish.)
