@andytheman, my vocal cords slowly paralyzed after radiation, and then having Covid twice. At first, it was a struggle to breathe. Yet, as it progressively worsened, even bending down to pick a flower became life-threatening. If it weren't for Primatene Mist Spray (while waiting for Tracheotomy surgery) I would have suffocated. Having a Tracheotomy is the best thing that could have happened. Now I breathe freely, plus any mucus is right there to be coughed out the tube. Before the surgery, the mucus was trapped. Best wishes to you.
