My husband has been breaking out in rashes in random places all over his body. These rashes will show up out of nowhere, and are very itchy. They last about 15-30 minutes, then they go away....and then show back up an hour or two later. This is day 5 of this same thing happening. They are showing up on his arms, legs, abdomen , back, groin , head, etc. No fever or other symptoms, but very uncomfortable when rash is present.
