My New Allergy

I had an infection last week and went to the doctor and he gave me some Amoxicillin. I have been taking Amoxicillin forever without a problem. Anyway, I have broken out into hives (well, not technically hives) and itching my whole entire body for about 4 days now. I am going absolutely insane. I went to the doctor again, for the itching, and they said they feel that I am allergic to the Amoxicillin. So, they gave me a stronger allergy pill for a month, and some prednisone for the itching. I am a tiny, tiny bit better but still a little itchy.
