Of late, experienced more frequently atypical
chest pain and much burping, wind etc which can last two or three hours and seemingly appears at random. Perhaps unsurprisingly often worse after food and movement. Had endoscopy, no hiatus hernia, and now await manometry test. Suggestion is it could be involuntary air intake , dysphagia mentioned, (no difficulty swallowing) causing build up of wind, hence pain, this makes sense but why? No heart problem.
