About three weeks ago I had to start walking to work, about seven blocks. It takes me around fifteen minutes. I stayed in the shade whenever possible. I would say about half the time. My skin peeled like a sunburn about a week later. I never turned red. My skin became sensitive and whelped in the bend of my elbows and under my arms. Now it just hurts and itches. What is the problem? I now use an umbrella when I am in the sun, but the sensitivity has remained.
