I've been dealing with some breathing issues and chest tightness over the past couple of weeks, especially after eating. It's like I need to yawn just to feel like I get a full breath sometimes, and there's also a little bit of chest pain here and there. My thyroid's fine, and I've never had asthma. Two years ago, I had the same kind of problems and saw a doctor who thought it was anxiety and gastritis. He gave me antacids, and that cleared it up back then. Could this really just be the same thing happening again? Any advice would be great.
