Thank you for the query.
Lower abdominal pain
can be caused by urinary tract infection
, large intestine disease (inflammatory bowel disease
, polyps, cancer), inguinal hernia (if located in the right or left side), abdominal hernia
(especially if you have had any surgery before, it can appear in the area where the scar is).
I suggest you to visit your doctor, have physical examination and start with basic tests. Blood work, urine analysis and abdominal ultrasound should be done at first. If no findings, colonoscopy should be considered especially if you have had any constipations, diarrheas or blood in stool
Abdominal CT might be also necessary.
Hope this will help.
