I think I had an allergic reaction to cider but not sure. Please help!

I drank only one cider, I can handle my alcohol very well, I didn t get drunk from it. About 2 hours after drinking it, I was overheating so much I needed to lie on the floor and had a really bad headache. I also felt ill when standing up. The next morning I woke up with a very sore throat, painful to swallow and yawn. I was also sick that day, the spewing gave a bit of relief but later on my stomach was more painful again and the headaches were still there. Then we are on to today, I still feel ill, my throat is still very painful and I have an upset stomach. I rarely ever get hangovers, never had one that has lasted 2 days, I m not sure if this is a hangover or an allergy because the symptoms I looked up are pretty similar (except I don t have diarrhea). Does this sound like an allergy?? Please help
