I've had my band since 2006 and am currently experiencing stomach pain. This is a constant ache in the center of my stomach. my Doctor removed all fluid from my band and the stomach ache went away. I then had an upper GI which showed no slippage or erosion. I returned to my doctor, he re-filled my band and instantly I had the same stomach ache. he said to wait and see if it persisted and the next step would be an endoscopy. Anyone suffering from the same symptoms? Any suggestions?
