I am a 24 year old male, and I've always loved to have an occasional beer with dinner. About 8 or 10 months ago, though, I started getting ridiculous hangovers (extended vomiting, headaches, etc.), after having only 3 or 4 beer. (These symptoms would never occur, however, until around 9am the next day.) So, I switched to rum and whisky, and the sickness stopped happening. Over the past couple of weeks, I've been testing my luck again, trying one beer on occasion, and nothing happened. So, two nights ago, I shared about 3 or 4 glasses of draught with some friends, and at about noon yesterday I quickly broke out in a strange skin rash -- 100's of small red spots (like small blood blisters) from my shoulders to my knees. They are still there today, although it's not getting much worse now (I've been taking an antihistamine, and I'm awaiting the results of a blood test).
Are these normal occurences? I suspect I might be allergic to something in the beer as it digests... But, I have noticed that these weird things have only occurred when I'm drinking domestic (Canadian) beer, while imported European beers have never yet affected me like that... Any thoughts on this would be appreciated! Are there different ingredients that might be doing this? I really hope I there something I can do...
