To answer your questions:
1) Possible causes can include gallbladder disease, including the bile duct obstruction, as well as various causes of dyspepsia - GERD, an ulcer, or inflammation of the upper digestive tract. Of course, the pancreas can lead to pain in that area as well.
2) Finding the cause of the pain will help. If all the GI diseases have been ruled out with the appropriate studies, efforts can then be focused on pain relief - including adjusting the dose of the duragesic patch.
3) I cannot quote specific online support groups, but there may be others that can comment here that may be able to help.
I would discuss these diagnostic options with your personal physician.
Followup with your personal physician is essential.

Thanks for all the information. Greatly appreciated. Today the GI doc started Reglan before meals. We are hoping that might help. He was concerned about gastric emptying problems.
