I am a 40 year old female and have just recently experienced some symptoms that seem like an allergic reaction to beer. I've been a social drinker for many years, but recently it has been strange for me to have one or two Bud Light Limes. Tonight I drank 1 beer, my face instantly became flushed and I have nasal congestion. About three weeks ago, I had three beers and I experience a very flush face and the worst headache imaginable. Could I all of a sudden become allergic to beer? And what can I do to get it tested? I know I could just stop drinking beer, but I like to have a couple here and there. Please advise.
