urinary tract infection
"Took one 250 mg tab of levofloxacin at 6 p.m. yesterday and am still experiencing side effects 18 hours later. My symptoms are reduced but are replaced with a 6 out of 10 on the pain scale- stomach ache. I have nausea, heart palpitations, dizziness, headache and joint aches. Ive called my doc back today to see about getting alternative med. I will not take another dose of this medication."
