I think the lump in your throat may well be from acid reflux. it can take quite a while to show up as esophagitis or inflammation. I would try to take some Maalox Max and see if that relieves it. When I have a lot of gas I also get that feeling until the gas is gone. After years I know that is what it is. it is an awful feeling. I was diagnosed with severe esphagitis infact Barrett's esophagous which is considered by some to be a pre-cancerous condition as people with Barrett's have a higher incidence of cancer. It was what they call short segment but in any case I was not even aware that I had acid reflux as I never felt heartburn or tasted acid in my throat but this was obvious that I had it over years. Well, my last 3 endo's showed none and no inflammation but there is no question that I still have the reflux. I take Prevacid in AM and Pepcid in PM and Maalox Max. There are ways to surgically correct acid reflux by tightening the sphincter but at my age and with my other medical conditions I would not attempt it so I have many endo's to keep a check but I do still have reflux.If you have reflux you need to immediately stop chocolate, alcohol and anything mint as they relax the valve and let the stomach acid back up. the valve gets floppy. good luck.
