I am sure a have a Urinary tract infection and my lower back started hurting so I think it spread to my kidney, I just bought some medicine for the ut?
Need urine culture. If the infection has spread to your kidneys, you need to get SPECIFIC treatment immediately. Your doctor needs to get a urine culture to find out exactly what type of bacteria is causing the problem and then use an antibiotic that will kill that specific organism. Nitrofurantoin and sulfamethoxazole/trimethoprim are generally good. Treatment must be long enough to fully clear the infection.
