urinary tract infection
"Taken 3 doses of this stuff for UTI 
It's godawful... I went to work with a boiling forehead and headaches, took some pain pills for the headache but my forehead still felt like it was melting off. Go home, take my third dose, headache comes back and is wicked... my tongue is cramping and my throat feels strange, I'm afraid to fall asleep. Never taking this stuff ever again."
