May have spoken too soon.. There is some ongoing tiredness, and what others describe as a head cold. I have not heard that term, but describe it as pain in the sinuses above the nose, behind the forehead.Feel very good. Back to normal.
Tiredness is not enough to climb into bed but it does subtract something from life and daily productivity. I initially started to worry, what if my system is now truly stuffed up by covid. It's probably hype though that covid causes other effects after it has cleared up, as nowadays you can barely trust anything you read. Should I regret going visiting a totally packed, maskless place and semi-deliberately catching covid.. Well, was going out of my tree with the madness so had to do something.
When I was in my late twenties I seemed more susceptible to catching a cold and taking a while to get rid of it. Then in my early thirties when really living the single life, I caught 'mononucleosis' aka the 'kissing disease'. That is a virus and some people believe it is linked to something called 'chronic fatigue syndrome'. That virus was confirmed with a blood test. It was an initial fortnight, but I remember tiredness going on for months. Never worried that I had CFS but did do some reading at the time about viruses and fatigue. But eventually it went away completely and for an entire decade I was very robust against flu and viruses.
So I'm hanging on to that thought as reason to believe that this lingering tiredness from a Chinese man-made virus will also clear up over perhaps months.
