I had a rash on my arm, and my doctor prescribed prednisone (12 days ).  I finished it a week ago Sunday, and the rash is coming back.  He said its an allergic reaction, but were not sure to what.  Will this go away on its own?  Is there something I can put on it?
Hello, Thank you for asking at Chat Doctor. I went through your history and would like to make suggestions for you as follows:1. If you have these complaints for the first time, I would prescribe you an antihistamine like fexofenadine or HY Chat Doctor. 2. I would also suggest you to apply a lotion like calamine over itchy areas.3. Please do not scratch the itchy areas as it aggravates itching. 4. If you have recent intestinal symptoms or recent travel, I would suggest you an antiparasitic medicine for 3 days as sometimes intestinal parasites can also cause such symptoms.5. I usually use corticosteroids (prednisolone) for resistant hives/rashes. I do not prefer to use them as first
