2 years ago, I remember laying in bed having this really weird feeling in my chest, all of a sudden I felt this insane tightness in my chest to the point where I couldn't take a deep breath or expand my lungs. Over the course of the next couple weeks I started to develop a cough but never went to the doctors for it. 

Every since then I haven't really been able to breath right or expand my chest how i used to. I've been to multiple doctors specialists(cardiologists, Gastroenterologists) ER visits, Urgent Care visits and everything has come back normal, besides having hypothyroidism.

I'm starting to feel hopeless and lost even though the test results come back normal and healthy, I don't feel healthy. I can't take deep breaths in and a lot of the times I have to manually breath.

Anyone going through anything similar? Thanks
