Anyone knowledgeable on allergies?

[disjointed]

This is a bit random, but I think I'm allergic to alcohol. When I drink, I typically drink things with vodka in it (but I've tried other things), and I don't drink much -- after a sip or two, I start to feel... odd. My face gets really hot, I get clammy, and hot and cold chills, with lots of sweating. And... to be frank... my pee-hole burns (sorry if this offends anyone!). Should I go to my doctor, and get tested or what? TIA!
