I've got the same thing. Bumps that itch like crazy on my arms, armpits, neck chest. Been to the doctor was. Diagnosed with "stress related hives". I was put on prednisone after the cortisone creams and baths didn't help. The steroids helped but the side effects were horrible. Now the "hives" are back. Bumps and dry skin so itchy that I have scratched myself to the point of bleeding.
I've tried every thing...new detergents, washing bedding and clothes, vacuuming, etc., oatmeal baths etc., benadryl....Nothing helps. It's driving me crazy. Any help / advice would be greatly appreciated....
