It just kills me when things are so obvious... sigh ( I am talking about "obvious" to your doctor, not you)... you are having twisted bowels sweetie!! THAT is why you are backed up and in pain!
I notice you are "BELOW GOAL." This happens a LOT to those of us who get "too skinny" or below goal and then get some rebound. When we loose a LOT of weight too quickly, we lose all the fat that cushions our intestines and keeps them in place. When all that fat is gone, it creates "voids" in the intestines and causes our bowels to move around like "snakes in a snakepit" They kink, unkink, kink, unkink. After FOUR years of this I finally found someone who would tell me the answer other than you are "FOS" (full of ****).
This will NOT show up on any test... even when it is happening. The only way to find this or fix it is by exploratory surgery. I know surgery sucks, but believe me.. it is BETTER than suffering everyday and to make it feel like it is "all in your head."
Sure enough, when they got in there.. they found I had a "hernia" (void) in the Mesentary/Petersen's space. They also cleaned up some adhesions/scar tissue that was pulling on some of them and causing them to kink.
Your colon is working.. it is just getting kinked!!!
the clue is "BENT INTO TWO".. as in .. "the fetal position" even with RX! Demerol wont even touch this pain!
I have been pain free now for a year thanks to a surgeon who would listen to me. He "tacked" all my intestines down so now they don't move around so much.
Please don't ignore this anymore. We just lost someone here on this site who died from twisted bowels. I can almost GUARANTEE you that this person had the same symptoms!
