Health oddity right here. Medicine is a science *shrug*.
Likely Covid, but it's still an odd experience.

For a few days now when I breathe I sometimes exhale for a split second. Like the diaphragm spasms once.
Or when I talk it would seem like I don't have enough wind to finish the sentence.

Can take a big breath and it doesn't trigger any cough.

Overall feels like I have pressure in the chest. Something you can have but goes away with a solid intentional clearing of the throat.

Is this the so-called "shortness of breath"?
