I have broken out in hives from my scalp to my legs after drinking 1 beer on 3 separate occasions. First time, I had eaten peanuts, too, so I suspected the peanuts. The second time, I just drank a beer. The third time, I tried a different brand of beer. Then, yesterday, after eating pasta, the hives returned with a swollen lip as well. I am 38, and go into anaphylactic shock from penicillin. So, I m wondering if I need to see my family doctor, or an allergist for testing.
