I had a reaction to amoxicillin yesterday (I had never been allergic to it in the past). I had a swollen tongue fever, chills, dry heaves and diarrhea. The fever has gone, as have the chills, the swollen tongue and the dry heaves. I have very mild diarrhea as I begin to eat again. I do, however, have some tingling in my face. There is no rash but it is annoying. It itches but when I touch or rub it it goes away at that particular spot.
