I had poison ivy ( it spreaded very badly), and my doctor prescribed prednisone, for 14 days. Day 12, I noticed a reddish rash on my stomack. By the way, I am very healthy and extremly active, never had any skin problems at all. The following 4-5 days, it was all over my body, tried vinegar, oatmeal bath, hydrocortisone, baby powder, aloe vera ( the plant itself), nothing really works. I'm going back to my doctor in am. Not a lot of sleep last couple of days. I'm wondering: is it a prednisone side effect? I can see that way too many people have the same situation. Any thoughts? Thx
