Amoxicillin and upset stomach

I was prescribed amoxicillin for a sinus infection. (3 x 500mg / day) The good news is that the sinus pain was relieved within two days. On the other hand, I developed several side effects, which seem consistent with other reports I've read on this site. These include the common complaints of diarrhea and upset stomach. In addition, after about two days I started to experienced symptoms of a fever, including general body aches, slight head ache, chills and skin sensitivity, especially on my back. The strange thing is, I don't have a fever (temp. 97.9F). These symptoms seem worse at night. I suppose I could have some type of virus along with the sinus issue, but it seems strange that the onset of symptoms was so coincident with the amoxicillin treatment.

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.

i feel like i have the flu (aches, chills, pains, fever,vomitting, upset stomach) but about 100 times more gloomy in my head and sleep barely feels comforting. this only happened after about 5 days on 2000mg for a nasty sinus infection.
