I have very severe pain in my stomach region that is in the general area underneath my rib cage and directly in the center of my abdomen, and the pain will also very often radiate into my lower back. I have had an Upper GI and ultrasounds but Dr.'s are still not able to provide a diagnosis other than it is NOT just acid reflux and an ulcer has not been ruled out. I have taken Protonix on occasion which does help, just not every time. The amount of pain has increased dramatically over the past few weeks that I'm almost incapable of doing anything but lay down. If anyone has experienced symptoms similar to mine and can offer any advice to discuss with a physician, I would be so grateful. Thank you in advance!
