Hi - whenever I have a drink of alcohol, my face turns bright red. Could be as little as a 1/2 glass of wine, or a beer. If i have something stronger, say a margarita, it happens quicker. I and am otherwise 100% healthy - what could cause this? Do I have an allergy to alcohol? This has happened a few times in the past few years, so I just generally skip having a drink. Not the same as a hot flash - just my cheeks flare up red.
