Pain in the area three inches below the navel may be caused by intestinal spasm or gastrointestinal dysfunction, which requires a visit to the gastroenterology department. Urinary tract infections can also cause pain in the area three inches below the navel. Routine urine examination and ultrasound examination are needed, as well as routine stool and abdominal fluoroscopy if necessary. The same situation can occur with cystitis, which requires colonoscopy and ultrasound to confirm the diagnosis, and needs to be seen at a local regular hospital.
