I'm very concerned about having esophageal cancer. In 2009 I didn't have trouble swallowing or food getting stuck that i can remember, but I did have that constant lump in my throat feeling for about a whole month. After an endoscopy I was diagnosed with grade B esophagitis, normal biopsy, and put on nexium 40mg once a day. Any time I try to go off of it now, that lump feeling comes back, I lose my appetite mainly because I feel like heaving, and can't really burp, or it's foam..
