HI Minnaas ! Sometimes there are post operative adhesion formation at the site of operation which might stick to a part of your intestine, causing it to twist and get obstructed causing pain. It might be of sub acute nature giving rise to intermittent pain or it could be acute giving rise both to pain and acute intestinal obstruction resulting in absolute constipation and inability to pass gases as well with distension of the abdomen. I feel that in your case it could be sub acute in nature because of the long duration of your pain since the operation more than six months before. However, there are many different pathological processes which could give rise to such pain in the abdomen, which if could not be diagnosed clinically, warrant for further investigations like plain X ray of abdomen, ultrasound of abdomen, and a urine culture and sensitivity test to exclude various other conditions giving rise to such abdominal pain. I do not want to confuse you by giving all the details of these conditions , but you can always discuss with your treating doctor on these points. If nothing is conclusive, then a diagnostic laparoscopy may be helpful. Wishing you an early recovery. Thanks and good luck.
