I am so very sorry for your pain and pray that you have already received an answer and some type of treatment plan. I will tell you that the pain you describe sounds very much like acute pancreatitis. I repeat this often, but women who have experienced child birth, kidney stones and pancreatitis are first, very unlucky, but, everyone has told me that the pain of pancreatitis is the worst. Mine begins just below my rib cage and radiates into my back and eventually seems to envelope my entire abdomen. The first major acute attack I had began on a Friday and I am surprised I didn't OD on antacids, because it began as if I was experiencing either a heart attack or my esophagus was going to rupture. I don't like to cause panic, but if you have not had an endoscopy where a scope has been used to look at your pancreas, I would request one immediately. I had a tumor that required the removal of about one third of my pancreas and had not been see on my annual CT scan. An endoscopy doc was going to give me what is known as a celiac plexus block and discovered the tumor. Thank God, it was benign, but pancreatic cancer has the highest mortality rate of all cancers, to my knowledge and the primary reason is that doctors who do not see it in high volumes don't recognize it. It also still carries the stigma of being an alcoholics disease and uninformed physicians assume, incorrectly, that even with the correct diagnosis, the individual is still going to slowly kill themselves. I have a congenital defect that causes poor drainage from my pancreas known as pancreas divisum. Find the highest volume center for dealing with pancreatitis, that you can get to, and get there. If you have a relationship with your PCP or any other physician, ask them to please do an endoscopy just for your peace of mind and I would think your combined different DX's should get insurance approval for one. I also have IBS-C and there is no comparison of the pain. Chronic blockage may cause some pain, but it does not rise above discomfort for me and I know how to eventually solve that issue. Please stay in touch and let us know how you are doing and you certainly have my prayers.
