I am 20 years old, & yes, I understand the under age drinking policy, which isn't something that I need to hear when answering about this subject. Occasionally(doesn't happen -every- single time), when I drink alcohol I get chest paints so severe that it hurts to breath, & I feel this tightening in my chest, AND in my neck muscles, where it hurts to turn my head. This can happen after one drink, a few sips. After about 20 to 30 minutes,the pain seems to diminish and I can't even tell that it happened at all. Could there be an allergy to certain brands of alcohol, or the color of alcohol? I think it tends to happen more with dark colored alcohol brands. Could it be some sort of heart burn or acid reflux?
