urinary tract infection
"My third UTI in three years and this is my least favorite medication (I've had different prescriptions each time) although I guess it's working... I'm on day 2 out of 3 days only and urinating isn't as painful as it was the first day. BUT. the side effects from this medication are awful. I normally am never affected by side effects from any antibiotics but these are making me feel sick, nauseous, and weak all day."
