What's wrong with the pain in the lower abdomen when you go to the toilet?

When you go to the toilet, abdominal pain may be caused by factors such as excessive bladder filling and urine retention, or it may be induced by diseases such as acute pelvic inflammatory disease, cystitis and urinary tract infection. You should be admitted to the hospital for urine routine and abdominal color Doppler examination. If you are diagnosed with urinary tract infection, you should follow the doctor's advice for oral antibacterial and anti-inflammatory drugs.
