Hey there @kailalange - There are tons of posts in this thread and it seems that most people have a similar symptom dealing with SOB, chest tightness, hard to get a satisfying breath, etc. The tricky thing with SOB is that every single person in this thread could be dealing with something different. Some people may have anxiety, GERD, mold in the house, some sort of hyperventilation disorder, liver issues, etc. I've also been on omeperazole for a couple of months and I think it helps a little but it's hard to verify. Some days I barely notice my breathing and other days it's all I can think about. @gabrielm says that the buteyko breathing method has helped him but not totally cured anything. Personally, I've given up on going to the doctor. I've been about 5 times over this same issue and gotten multiple opinions. My main focus has been to try to experiment with what I'm eating, drinking less alcohol, trying to lose weight, trying out different breathing exercises, etc. There are some people in this thread that have been to every type of specialist you can go to and gotten every test in the books and still don't have an answer. It's a little discouraging but I feel like if we all stay in communication, experiment with different things, we can move closer to improving our quality of lives.
