Hey surfgirls, I have something similar to you. Do you ever feel as if the burp is stuck in you? Like you can't make it come up? That's how mine usually manifests itself, but I also, like you, am constantly belching. My doctor thought it was reflux, and he was right, but not entirely. I did have ulcers and esophagitis, which indicated reflux. I tried Nexium (made me feel TERRIBLY SICK) then I tried Prevacid which healed my ulcers but has not stopped the belching problem. I am seeing a new doctor who thinks it might be gallbladder or gastroparesis. By the way, do you have any other symptoms, irritated throat, hoarseness, anything like that?
