It sounds like it might be a food allergy, or an allergy to soap, make up (if you're female) or a hundred other things. I can tell you right now though, if all you have is flushing, you will not go into allergic shock over it. I had this happen to me back in college. I was flushed and kind of warm feeling. I went to the doctor, and got some steroids, it went away in about 2 days. I would write down everything you've drank, eaten, or put on your body (soap, shampoo, make up, etc) and go to the doctor so they can figure out what you're allergic to so it won't happen again. You won't die from it though, I promise. I had a reaction like that, and I'm still here!
