Trey....
Glad you're feeling better. I thought my two weeks with Covid was tough, but yours far exceeded mine!
I've heard both sides, but the other day, I read an article in a medical journal that claims if you've had Covid, your T-Cells will attack the Covid virus. My takeaway is that you'll be immune from Covid for a long, long time.
Digressing here...it will be interesting to see if you have any long term affects from Covid. I did not have any of the breathing issues you had, but did have just about every other symptom over those two weeks.
It's been three months since I've been 'cleared.' As of today, my sense of taste/smell is about 2/3rd's what it used to be, I have diarrhea more often than I used to, and very unfortunately, my stamina just isn't what it used to be (which sucks because I'm a very active person).
Good luck with your recovery!
