Have had refux for years and take proton pump inhibitors.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. Also can experience missing pulse beat, no doubt to do with oesophagus.Disconcerting and irritating. Anyone, please, had similar and any suggestions before my tests?
