Hi, I have had stomach issues since I was little, my doctor at an early age diagnosed me with nervous stomach, then when I was about 18 or 19 I had gastritis. Since then I have had some problems with my stomach off and on, and in the past several months, it has increased and seems to hurt more often than not. I have a dull, sharp pain in the top of my stomach that will sometimes move to my right side just under my rib cage. The pain will often shoot into my back and sometimes into my right shoulder. But the pain is more in the top middle of my abdominal area, and can run into my chest almost like very bad heart burn. My doctor has put me on omeprazol but it has not done anything. Does it sound like this could be my gallbladder or something more?
