I was lucky in that I didn't get the lung infection. The sore throat was the worst of it for me, but all of my symptoms were pretty consistent with a generic virus, which lingered for about 10 days. In that regard the actual Covid infection can be defined as a mild-to-moderate one.
The complication was that after the virus was flushed from my body, my immune system was still a bit haywire and kept attacking my joints and muscles.
What was worse, the virus or the aftereffects? Kind of a coin toss in my case.
At any rate, it's all behind me and I have some antibodies for my trouble.
