Hello I have bumps on my arms, chest, and scalp. The bumps itch, burn, and leave large welts. I went to a doctor and he gave me medicated lotion (Triamcinolone Acetonide Cream) which only takes the burning and itching away for a very short period of time. I went back in today and they prescribed Prednisone 10 MG tablets. And I am wondering what these bumps are... I've never had a history of allergies to poison oak, or poison Ivy, which is what the other doctors said it was but my husband does everything I do and is around our dog and he is severely allergic to those two things and is showing no sign of the same symptoms. Do you have any idea of what this may be?
