I also suffer from the same thing, it has taken over my life too. I had to have emergency colostomy surgery due to a severe supermegacolon episode. I have tried lots of things, now I am using narcotics to try to manage the pain, most of them only have helped some. I am still searching for the right combination of medication that might provide some relief from the constant pain. I have also spoken to 2 different surgeons for their opinions, both tell me it is not a sure thing. So until the pain management Doctors run out of options I have just put the surgery on hold for now. The thing about eating and the increased level of pain, I do think they are related. It has been confirmed that the cause of my pain is post surgery adheasions, so I just keep trying to get this under control, and it is very frustrating. hope things get better soon.
