@gabrielm yes I'll definitely be looking into the buteyko method.
Air , from what I've learned, can get trapped in your chest cavity, it can cause pneumothorax (or collapsed lung) , spontaneous pneumothorax can be caused by a blister or a "bleb" (yes that's the Actual medical term! Lol ) bursting on your lung, and the air, instead of being pushed one way, it goes another way and can cause sob or can cause your lung to collapse. So originally this is what my doctor thought it was. But I think that's becoming less obvious since I still have sob and it doesn't seem to be getting better. (I guess these things tend to resolve themselves within 6 weeks.) Maybe it was a coincidence that they found the air trapped in my chest cavity and it has nothing to do with my sudden sob, or maybe it does! Who knows. Certainly not my doctor lol.
I feel like I'm learning more reading through everyone personals experiences on this thread than my doctor ever told me.
Happy to be here!
