I am 21 yrs. old and I thought I was in good health. I run everyday and eat right. About two months ago a coin sized patch appeared on the back of my right knee. It was extremely itchy and dry. It got so bad that I scratched it until it started to ooze a yellowish liquid. I was given prednisone and it went away. As soon as I went off the prednisone the patch returned but smaller and I used hydrocortisone and it went away. Then another two weeks later I noticed very small (you can't really see them at all but you can definitely feel them) itchy white bumps appeared sparingly on my arms with small patches of bumps and sometimes dry skin around the areas. It wasn't that bad until I woke up one morning and they covered my entire body, including my ears. I have it on my chest, neck, stomach, legs, thighs, back. It itches sooooo bad that I haven't been able to sleep more than two hours a night and I take at least three cold showers to help ease the itchiness. I always moisturized before any of this happened (everyone always said I had really soft skin) and then this happened. I live in Hawaii and now I have to dress like I live in Alaska. It is not on my face or feet but a little on my hands. What is this? I can't stand it and now I think my depression is coming back because of it. Am I allergic to something? I've been taking Benadryl and I use Aveeno Body Wash and lotion but it doesn't help it at all. I've had the entire body rash for about a week now and it's not clearing up at all. I was sleeping at my boyfriends house and I thought it was because of his soap or sheets but I don't think so. Why would this all of sudden happen. I have never had a problem with my skin. I never even had acne as a teenager. Also, the rash on my neck refuses to go away. I've had that since I had the patch behind my knee. The doctor said they weren't related but I think they are. Should I just ask for more prednisone. That seemed to work really well when I was on it.
