Amoxicillin and allergies

Two weeks ago I came down with a really bad case of strep throat. It started out with headaches (which I thought were migraines), then I got the sore throat, and by the time I was able to get to the doctor it was very severe and they put me on 875 mg of Amoxicillin twice a day. I started to feel better and the sore throat went away very quickly. I'm generally I very healthy person and have no allergies, so I did not even consider that any adverse side effects were possible for me. However, about 8 days into the 10-day cycle, I came home in the evening and began to change when I noticed red spots on my chest and shoulders. I quickly made the connection and got on Benadryl, but the rash spread quickly. The next morning I woke up with swollen lips and swelling around the eyes, as well as small reddish swollen areas all over my face. By Sunday it had spread to my legs, where it was by far the worst. It is now Wednesday, and it has faded a great deal above the waist, but it looks horrible and discolored from the waist down and my doctor told me it might take "a while" (a week? more?) to clear up completely. I have also noticed that I've been bruising very easily (I have marks all over my shoulder from the strap of my shoulderbag, which is not even very heavy, and I do NOT bruise easily under normal conditions.) It's making me pretty miserable and I can't stop looking at my legs and wondering when they will look normal again.

Also, I got the upset stomach (not too badly though) and a mild yeast infection.

I wish doctors would not be so free and easy will antibiotics.
