I have that same problem as bbubbles1969!! since september of 2002 i've experienced a very sharp pain that starts in the center of my back and goes straight through to where my gallbladder was. sometimes with nausea. doctors say everything is fine and tests for h. pylori have come back negative. i had my gallbladder removed in june of 2003. the pain is still there,only now it's sharper. what is causing this!!
