diverticulitis
"I appeared to have a kidney infection because of the pain. Dr gave me metronidazole but the side effects were horrible - I thought I was having a heart attack from the pain/pressure.  Amoxicillin was tried but 3 weeks later little better.  When I ran out of Amoxicillin within 24 hours I was in horrible pain again and went to the ER.  Like others the Dr said everything is GREAT, you can go home.  No way I feel like crap so he did a CT.  The CT showed diverticulitis.  Vindicated!  But then he prescribed Cipro and metronidazole.  I'd taken Cipro last year and it destroyed my knees...I was on crutches for months.  Trying just the metronidazole, still feel crappy, but pain is going away.  Why not Augmentin?"
