Hi, following your post as am currently experiencing the same burping problem as you with a feeling of a lump in the throat. It comes & goes too..hope you get more replies!

Sounds like the 'coping mechanism' you used for one issue has become an issue itself. You say that when distracted the breathing problem goes away. Its only when you focus on it that it is there. This is typical of behaviours caused by anxiety disorder. What you thought was helping you is in fact adding to your distress. But what you have described is a learned behaviour and, therefore, can be 'unlearned'. If you have a therapist, that is the best person to talk with as that person knows your exact situation and how best to help. If you are having something like acid reflux then I assume that your doctor is dealing with that side. I wish you well.

hey! I also suffer from anxiety. I had the same thing (the burping). I was forcing burps as a habit. It lasted a few months and eventually went away. This caused me to get really bad acid reflux. It will pass in time. Also, try taking an over the counter acid controller.
