About a month ago, I wore an undershirt that was new from the department store without washing it. The very next day, my upper body started to
itch like crazy. I went to see the dermatologist and took prescribed medicine for about three weeks. Two weeks have passed since I last took medicine, the rash is subtle, but I think it's spreading down to my lower body. I don't know what to do. I can barely see the bumps. But it itches a lot.
