It's been a month now. I have bumps under my skin that itch so bad I could dig holes in my arms. I've tried hydrocortosone, doesn't help. Right now I've got milk of magnesia liquid smeared on my arms and it helps cool it a little. When I gets really bad I put ice on my arms. I've read up on sun allergy, and I'm thinking that might be the problems. Most people start itching from late spring to fall and then it goes away. Anybody have a solution?
