I have been prescribed to take levofloxacin as I am suffering from more urine frequency and pain at times. I know UTI is not common in males but I am going through a bad days with the pain in pelvic region. It's my 4th day of 750mg levofloxacin. I see no improvement in me and still suffering. Can this be a kidney stone? Having increase in urine frequency and pain after urination.
