I was recently diagnosed with a UTI I have never had one before and it has been many years since I was on any antibiotic at all. two years ago I had a severe delayed hypersensitivity allergic reaction to the medication Diamox so they assume I am also allergic to sulfa. So they tried me on Keflex and I could not tolerate the side effects, they tried Macrobid I could not tolerate the side effects, and then gave amoxicillin Which I know I have been on in the past and not had a problem other than mild diarrhea but three days into it started having severe skin burning sensation all over my body and a very red face and this is exactly how my severe allergic reaction to diamox began. also I cannot take Cipro or Levaquin because I have Ehlers Danlos syndrome and floroquinolones are contraindicated due to their adverse effects on tendons and ligaments joints etc. So if a person is allergic to all these, what can be done???
