I have had red spots on my back, then my arms. They are about the size of a dime. After a couple of days, the become blisters then go away. I also feel real tired to the point of exastion. My Dr. has had me on Steriods 3 separate times for the spots, which they clear up until I m finished with them, then they reappear. They don t itch, hurt just embarrassing.
