I'm just joining in this thread for the first time.
So my symptoms are weird because I had Covid back in late March. The loss of smell and taste returned after a fortnight or so and the cough lingered on until about June/July. I had a very severe period of acute depression (where I tried to kill myself) from April to June. The shortness of breath post-Covid never really went away.
Then over the summer hols I was reasonably okay... apart from the lung capacity thing and the weird pulsating nerve "whoosh" that would spread over the back of my neck and ears whenever I lay down. But I could live with it... and tbh didn't really think I had long-Covid.
Then I went back to work. That was the thing that really did me in. My shortness of breath is horrible, and to compensate my diaphragm goes into spasm every 15 mins or so. Cough returned and is lingering again. And my chest is in almost constant pain, with regular stabbing feelings. My blood oxygen level sometimes drops to 94, esp if I exert myself but it's not low enough to be a problem (and I should probably stop checking). Oh and the tinnitus. The fecking tinnitus!
If I walk on flat ground I get massive bpm raises but I don't feel particularly out of breath. Yesterday I was gently strolling with a friend and it was consistently over 150 for about an hour. But if I exercise properly its actually lower. I can't explain that because if I exercise, I pant like a normal person, but if I walk gently and feel fine, I get the bmp rise.
Just miserable.
