urinary tract infection
"Bactrim doesn't seem to help, have a UTI and Dr put me on Bactrim, even after I told him it didn't work for me in the past.  Been on it for  a week and I can barely urinate.

(Cipro has worked well for me).  Now the Dr. wants me to make another office visit,
because he gave me an antibiotic that I told him has not worked for me in the past.
I asked him to call in a script for Cipro, he won't.  He is convinced that if Bactrim didn't work, I need another visit. So now I have to pay for another visit.

I almost always test negative for UTI, which makes me wonder how inclusive their culture test is.  

Anyway, ask for Cipro if Bactrim doesn't work."
