urinary tract infection
"This is a serious antibiotic.  I have never had such adverse side-effects to a medication than I have with nitro.  I had a UTI that kept coming back for about 5 month.  Doc finally put me on Nitro after cipro and everything else didn't work.  I am on day 9 of a 10 day dose and feel like I am dying.  I can't get a good rest.  My lungs feel congested but I can't cough up anything and my cough is dry.  I get panicky and frustrated very easily.  I have ZERO energy.  My hair is thinning.  I am freezing constantly.
