urinary tract infection
"Never had UTI before but I heard it was awful. When I got it didn't notice symptoms until 2 days later. Lots of blood in my urine so I went to a minut clinic and was prescribed Nitrofurantoin. After the 3rd day all symptoms were gone. The side effects were bad: nausea, vomiting, and loss of appetite. I think maybe the strength was too high but the urinary tract infection is gone so that's all I care about."
