It happened again, I cooked some pancakes - fry pan. I got seriously SOB; kind of like that suffocating feeling. Yet my saturation was 95 96%, it did drop down to 94%. I'm sitting here nearly an hour later, still feeling SOB, w/O2 = 97%.
Also I had just taken my evening dose of Symbicort, and an hour earlier had a puff of Combivent.
