Sorry it has taken so long to reply. Yes, I had pain right under my right ribs with my bowel obstruction and yet never had any constipation or diarrhea. The pain started in that area and then seemed to move across my abdomen and then down. As a nurse, I have access to my test results and when I looked at my CT, I understood why that pain changed. With the obstruction to my bowel the bowel became dilated or stretched since nothing was able to move through. However, with the internal hernia prior to the bowel obstruction, I would have pain there and then sometimes it would move accross my abdomen, but the onset would be sudden and when the pain stopped it would be sudden. So, I imagine I was getting some partial obstruction from the herniation of the intestine that would eventually reduce itself and relieve the pain.
I would like to know how you are doing, so let me know if you can. Some of the docs don't seem to want to recognize this problem so if it has continued you may have to really assert yourself with your doc.
