The next one is for a large bowel obstruction.

I don't remember seeing any mention of the pain that you are having across the top of your rib cage (in regards to a bowel obstruction), but I'm not a Dr. I really hope that you can get some help somewhere.... In the meantime I'll just keep on praying that you get some relief from all of this. Best wishes.
