Hi
@Disreguard ,
This sounds like an expanding gas issue. You mentioned being gassy and belching - if you have GI gas, a nice burp should relieve the pain. Expanding gas in the stomach could also be forcing gastric contents into your esophagus, which could cause discomfort in the chest area. The more serious cause could be a recurrent pulmonary barotrauma (pressure injury to the lung), perhaps from a weak area of the lungs, leading to mediastinal emphysema, which is gas collecting in the center of the chest. The slow resolution of symptoms puts this a bit higher on the differential for me, at least from your description. I'd recommend that you get worked up for this. Do you live in Orlando?
Best regards,
DDM
