Go see your doctor: Phenazopyridine or Pyridium (phenazopyridine) is pain relief for urinary tract infections. Septra/bactrim is a sulfa-based antibiotic which is a good 1st choice (guess) against utis. However, if you're not feeling better after a few days, it's best to go back to see doc & get urine culture. This test will identify specific bacteria causing UTI & tell doc which antibiotic to choose.Also consider checking for stds.
