Hello. I am a 20 year old caucasian male (german + polish). I get very bad "asian flush." It doesn't happen all the time, maybe one in ten times of heavy drinking (a fifth is about my limit (40% alc/vol, or if beer, about 18 5% alc beers), sometimes more, sometimes less,  at 150 lbs), and it is not particular to the type of alcohol involved. My scars, especially, get red and swollen when this happens, and the redness extends from my face to my belly button. But the scars all over my arms and chest are really red and protruding.

My question is: Is this something to worry about? Should I go to the doctor? I don't feel sick or anything in this state, it's just wierd. I have the worst diet ever and smoke like a chimney. 2 Huge meals per day of shit food from my restaraunt or fast food. Does this explain anything? Anything I can do to prevent this (over the counter pills?). I know if I take advil, I am guaranteed to turn red like a monkey's ass, so just help me out here people. Thanks in advance.
