Hi. I have had unexplained itching for about 6 months. It is mostly on the back, upper arms, feet, under arm pits, upper chest. I have had every conceivable lab test and nothing has shown up. Just recently, I started getting hives when I have these itching episodes. They are made better by triamcinolone cream that I happened to have on hand. I cannot figure out any new food, soap, or other possible new allergin. I have some allergies to dust mites and pollens that I am aware of. These itching episodes are making me crazy! Any suggestions?
