I recently saw a surgeon after suffering for 1 year from pain on my right side gallbladder area which tests results were negative. Surgeon did a colonoscopy and EGD. Results from EGD is chronic duenitits (which is the small intestine under the gall bladder) that is still painful when stressed on the right side and mid stomach pain. Along with esophagitis, gastritis and hital hernia. You could have some of these going on and I would recommend an EGD and colonoscopy just to make sure as it is still painful and taking Nexium helps but stress increases acid which makes it worse.
