I have one of those finger monitors that always reports things as fine (>97%, almost always 99%). It is difficult to describe what I feel. It is almost like I feel I am being partially suffocated from within my sinus if that makes sense? Like there is an obstruction. There isn't though as I have rinsed them and had doctors have a good look and even probe around in them and all is good apparently. The only theory my doctor friends have for now (other than COVID doing lung damage) is I could have some hidden swelling in my sinus that is changing the air flow and causing my body to think it isn't getting enough air as I breath through my nose leading that to slow suffocation sensation. Apparently there is a condition people who have sinus surgery get which is very similar but I have avoided making it worse by researching it.
