I love you, Caladryl!

Well.. my allergic reaction has gotten worse. If I wasn't continually covering myself in calamine lotion.. I would probably have no skin left. I have no idea what caused this reaction. I haven't changed soaps, laundry detergents, deodorants etc. I guess it has to be the clay, but I haven't used it in a week! I'm not eating anything strange that I don't usually eat. My back was killing me for about a week and I started taking a lot of aspirin. It is the only thing that has changed. I usually take Ibuprofen. I feel like finding a good tree with lots of bark and rubbing myself all over it! Any tips on things to alleviate the itching or make this go away? I'll do anything!
