sinusitis
"Well it did the job, and then some.  It cleared up my sinus infection, plus I had the lovely experience of having severe acne on my back from the drug.  I never break-out.  Then, a week after I stopped the 10 -day medication, I have a UTI, and vaginal bleeding (in between periods). I think it is insane that medication for a simple sinus infection can leave to several other complications."
