Pain after passing urine is most likely to be related to a urinary tract infection. A urinary tract infection might be located in the bladder or in the kidneys. It is usually caused by bacteria. The symptoms that accompany a urinary tract infection include: frequent urge to urinate, frequent urination, and pain or a burning sensation during urination if the urethra is affected.
Pus or blood (sometimes invisible to the eye) might be present in urine if the urinary tract mucous membrane was damaged by the bacteria. If the kidneys are affected, then fever, fatigue, night sweats, pain in the lumbar area, and abdominal pain might be present, too.
A visit to a family doctor or general practitioner is recommended. A physical examination and urinalysis might confirm urinary a tract infection. A urine culture might be asked for in order to determine the exact bacteria and the most effective antibiotic.
