I've had a rash for over 2 months now. It looks like very tiny red raised bumps all over, and they are very itchy. At first they were all over my legs, but after seeing a doctor and being prescribed prednisone it went away and I felt so relieved. Unfortunately, a few days after I finished my prescription the rash was back, and it has now spread to the backs of my hands, between my fingers, my stomach, and under my armpit. I'm feeling discouraged about going back to the doctor because when I was there the first time he had said he wasn't sure what my rash was, he did blood work but it came back all normal. I have no other symptoms. What could this be? How long could it last? I am so tired of being red and itchy, as a 20 year old woman it's embarrassing and affecting my day to day living.
