I am new to all of this. My brother was diagnosed with esophagus cancer, so I asked for a scope, since I had reflux, too. They found Barrett's, and put me on 80 mg of nexium per day. It has cut the reflux completely, but all of a sudden I seem to have difficulty swallowing, and I feel like food gets caught in my throat, up near the top. I feel all the time like I have a lump in my throat as well. I never had a problem with this until I went on the nexium. Any idea if this is a side effect? It is driving me crazy. My dr plans another scope, but it won't be for a while and this is alarming me. Thanks in advance for any help.
