For complex reasons I cannot entirely remember I took Prednasone for a week, at the end of year one. I felt instantly cured. Prednasone is dangerous in the long term use context, so I stopped. And then Long Covid returned. I was still too fuzzy-brained to figure it out then.

Now it increasingly tempting , to conclude LC is an auto-immune inflammation, taking many largely predictable forms: tinnitus, foggy brain, rashes, lethargy, colitis and fatigue, in repeating combinations.

I will now try to find out more about non-steroidal and low-steroidal anti-inflammation, including but not limited to diet.
