This has come back for me after 5-6 months of it being non-existent. Again it's this constant need for a 'deep breath' but I can't regularly suffice it. I'm need to yawn or deep breath so often that my jaw / throat gets painful. The feeling makes my eyes tear up and my head feel a bit fuzzier than usual. It's so frustrating and requires me to regularly concentrate on my breathing. Again, I'm 100% sure I caught COVID in March 2020 and this appeared around 4-6 weeks after that - so I also worry it's an ongoing side-effect of COVID. I'm 26, workout regularly nothing excessive - just weight training 3-4 times a week and a HIIT cardio type session 1-2 times. But my breathing isn't problematic at all when I exercise. It's usually becomes more frequent and persistent after food, or lying on my back. But once it's there.... it doesn't go away.

I was put on medication last year for GERD, this also seemed to help a little. Anyone else in the same boat? Or does any of the above ring true? It's been back a week and already I'm getting concerned.
