hi, I'm really happy I found ppl who are experiencing the same thing I am. I've been having SOB since the summer of 2020. Im 30 yo and I've never had issues w my lungs or asthma. I initially thought this was anxiety. Reasoning behind it - the less I thought about my breathing, the less issues I have w it (like if I'm completely focused on something and not in my own head.) I also go through bouts where I'm fine and then its non stop. I yawn constantly to get that full breath or I legit gag. It also puts a huge strain on my shoulders, jaw, and mid back. I do have some issues w sinus aggravation. I'm very congested in the mornings, I've noticed during my bouts that the more I keep my nose clear - the better my SOB (using nasal spray, Mucinex expectorant, Sudafed, cough drops.) I can only relate the issue to hyperventilating when you feel you can't breathe. Almost like claustrophobia. I initially went and saw a regular doc to check my lungs and treat me for anxiety. Lungs are fine and I have been on Lexapro for 2 years now and it might help a bit but it doesn't really do much for my SOB bouts. I'm hesitant to get any other tests done bc it seems for yall that it was a waste of time lol like the doc office ain't the most fun to deal w. Ugh but I can see how breathing exercises help (which I do sometimes,) I also notice if I'm working on keeping a healthier gut (probiotics, glutamine, vitamins - B12 included, healthier eating) it does seem to help. Also, I noticed too much caffeine - makes it worse (of course I still drink my coffee every morning *sigh*) BUT it truly is still a mystery on what this is exactly. It really lowers my quality of life.
