I have been breaking out in red itchy almost welt like bumps for over 3 weeks. They look like bites, we have searched the bed, no bed bugs, no fleas, I am the only one in the family that has them. Sometimes the bumps are on my feet or my back. My arms & legs are covered. It is very uncomfortable. The doc has given me a steroid shot & steroid pills, I am also taking Allegra & Benedryl @ night. I had the shingles in the fall not sure if this is related
