I developed a skin rash localized to my arm, small itchy red bumps sort of clustered all over the outside of my arms, elbows and 1 or 2 small spots on my hands. I was put on a Medrol dose pack and the rash cleared up completely after 3 days. I finished the Medrol and 5 days later I was broken out again, this time only on my elbows and small spots on arms, but all over my back, torso and a few spots on my legs. What could this be? I am trying to get in with a dermatologist asap.
