urinary tract infection
"This medication is horrible. Went urgent care, the doc gave this med to treat kidney infection. Right after first dose I got a migraine and terrible stomach pains. I stopped taking after three days. Now, two days later I feel worse than I did initially. I can't see my dr for five more days. I think I'll go to ER, because I have fever and my kidneys are on fire. I read somewhere that this med is not for kidney infection. Guess I'll find out soon."
