Abdominal pain: The described pain can be caused by endometriosis, and also by pelvic adhesions (scar tissue binding organs together secondary to infection or surgery). One way to ascertain the cause is laparoscopic surgery. Endometriosis can cause adhesions also. Period cramps, loose bowels with your periods and mid-cycle pain are symptoms of endometriosis.
