Hmm wondering too what this may be?? Here is my story. Anyone PLEASE respond if you may know...

I am having some recent issues and have no idea what could be wrong. It started on Wednesday night, I had terrible stabbing pains in my right upper abdomen. I am over one year post-op with roux-en-y. I have lost a total of 157 lbs and and now weigh in at 155. (About my history I suffered with severe stricture to the opening of my pouch and had a total of 8 EGD balloon dilations up until my 8th month post-op. Since then I have been able to eat solids just fine. I had a tummy tuck 10 weeks ago and my stomach has healed very well.
I had the attack on Wednesday and Thursday went in to the ER for the severe stabbing pains. I was told that I most likely pulled a muscle and was given Bentyl a stomach muscle relaxer and Tylenol then sent home. That same evening Thursday I had another terrible attack and went back in to the ER. They did more bloodwork and performed a CT scan. I drank 500 mL of the special cool-aide. They said everything was fine and sent me home with Zantac and Zohfran for nausea and heartburn. I again had another attack Friday night and went to the ER Saturday (early this morning). They performed x-rays of my upper abdomen and told me it was fine. BUT apparently the kool-aid/barium lit up in the x-ray screen and they diagnosed me with constipation since none of it has passed through my system. I have had the kool-aid done twice before for previous CT scans and it always gave me severe dumping. However this time it didn't I feel extremely bloated and burning. I do not have a fever but am concerned of an intestinal bloackage or impacted bowel as I have heard that this is common for us to develop. Very worried! I have already taken two strong laxatives and now I am waiting to see if anything will pass. The doctor said that my intestines are sluggish. I am passing gas but otherwise just waiting as I have not had a bowel movement since Wednesday. However the attacks started on Wednesday and that morning I had a ribbony BM that became loose diahrea at the end. So I am very concerned and would appreciate any advice I can get whatsoever.
