My husband, who has no allergies that he knows of, started scratching himself the other night at a restaurant, took off his shirt, and saw that his neck, back and chest--mostly upper at this point--were red, and there were hives under his armpits, surrounded by pink. His wrists and the insides of his elbows were also pink. He went to the doctor who gave him some kind of shot. Within an hour, most of the redness faded.
The next night, whle we were in a new hotel, they came back around 6-7. This time, there were no hives, and the redness had moved downward a bit. It covered most of his back, his groin (especially at the crease below his tummy), and his entire arms were pink--red in the creases.
The redness mysteriously disappeared after an hour or two and just came back tonight, right before we got home--about 26 hours later. Now the redness has moved down again, covering parts of his legs and feet.
We can't imagine what might have caused this. The environment and foods he ate changed a lot over the past 2 days, and he hasn't been using any new hair/skin products.
I also don't get why the rash disappears for about 24 hours and then only stays for 1-2, or why it is moving downward.
Any ideas? Thanks in advance!
