I have pain on the upper right side of my abdomen, just under my rib cage. It was occasional but now is regular. It often wakes me up around 2 or 3 a.m., or if I get up at night the movement brings on the pain which is an usually anisolated burning pain, but at times radiates to my back. During the day the discomfort comes and goes with no direct cause but often I notice when I m fully relaxed its not noticeable. I believe I have increased gas and balboa ting. Would this be gallbladder ? I m 61 and in good health.
