Why does it hurt when I urinate?
A urinary tract infection (UTI) occurs when bacteria enter your bladder through the urethra.
If you have a UTI, the bladder tells the brain to urinate more frequently. This is because the bacteria overgrowth that caused the UTI irritates the lining of the urinary tract. It also makes your urine acidic.
The result is inflammation and pain or burning when you urinate.
