Question
For the past few days i have been experiencing breakouts on my skin, only on my two forearms. They look like very VERY small mosquito bites, and are red. they usually form in a huge circle or other odd shapes. They only appear on my two arms. They come for about an hour or so then disappear. When they appear they itch and burn. Both my aunts are Nurse PRs. They both said it cant be hives because it looks nothing like it. Is there any other diagnoses it could be. I have been eating the same food, using the same bathroom products.
Only thing new i have been taking is percocet, but that would not cause this effect. I had poison ivy about 3 weeks ago on my arm. But that went away because i took prednisone. A week after it went away these started to appear. Could that be somehow linked? Could this breakout  be appearing through stress? Any ideas would be much appreciated.
