Tc, the skin peeling thing is ok, don't worry about it. When I had my surgery they put normal dressings over my wounds and then, because I wanted a bath, I put waterproof dressings over the top. I got a reaction to those dressings. The skin went pink, it looked a little blistered as well. Then about a week after the dressings came off, the skin went dry and peeled off.
Don't scratch at it, or try and peel the dry skin off. Just moisturise the areas. Use something like savlon.
And eat something. Try some protein and slow release carbs. Avoid coffee. Try not to smoke too much (easier said than done ... I'm in the same boat). xx
