Wind in chest area

Weird one, but have GERD and have it under control but at least once a week I have a really strong flip flopping in chest and go a bit hot and cold, then can feel wind and quite often burp or let off wind 😳 All tests show heart fine, just wondered if any one has this as the feeling in chest is very scary. Only last a minute if that. Not sure if GERD related

Sort of. I do feel out of breath afterwards and need to cough, as if I have asthma or something. Aldo get the cold sensation. I have had every heart test going and it’s definitely not that or so cardiologist reports. It even happened when I was wearing a monitor for 28 days several times but nothing was picked up.
