Lurker for years, my first post on this forum.
I had the sae thing in late January. Extreme stomach discomfort that started quite suddenly leading to bouts of vomiting. I couldn't even drive myself back home without puking into a bag. The stomach discomfort got better in 24 hours (mild fever also went away). Then the coughing started which later days. I'd wake up at nights to cough for few minutes each time. Chest tightness also began. I'm a lot better now, but my chest tightness isn't fully gone. If I fully relax my body I can feel a tiny bit of resistance to talking in a whole breath of air. I also have asthma and using my inhaler helped!
CorpRaider, keep hope and stay happy. Positivity helps the immune system. Thank God for Netflix. I watched a ton of comedy when I was going through the bug, whatever it was. Stay hydrated!!
I never considered Corona seriously but it does look like the symptoms are correlated. Now if there was community transmission in late January, just imagine how off we are with the denominator. I've been thinking about this a lot lately. The hard thing with exponentials is that it's easy to be way off if we are even slightly off in any parameter. What if we are wrong on the start date by a couple of weeks or so?
Orthopa's anecdotes and line of thought seems reasonable to me.
