On Monday I walked with a group of friends. First I walked down from my house to the coffee shop, walked with them, walked back. It was cold but I was well layered. I want to see if I can up my exercise in spite of Long Covid and muscle weirdness. The initial reaction was fatigue. I took a nap on the couch from 2 to 6 pm and then went to bed at 7. I woke at 5. Fourteen hours of sleep.

That is not totally reassuring. Tuesday I did not feel particularly sore or tired. Wednesday, though, was bad. I started have muscle aches all over and I could not get my hands or feet warm. I lay down under an enormous pile of blankets and eventually went to sleep, starting at about 2 pm. I woke at 9 pm and then went back to sleep, warmer but aching, until 4 am. So that is another 14 hours.

This morning nausea and headache, but less soreness.

So, here is an article: https://www.nature.com/articles/s41467-023-44432-3 about the post-exertional malaise in people with Long Covid. They took people with Long Covid, matched them with people who have recovered from Covid-19, and then did muscle biopsies in both groups before and after maximal exercise. Results? “We show that skeletal muscle structure is associated with a lower exercise capacity in patients and that local and systemic metabolic disturbances, severe exercise-induced myopathy and tissue infiltration of amyloid-containing deposits in skeletal muscles of patients with long COVID worsen after induction of post-exertional malaise.”

Both groups were healthy before Covid-19 and physically active. The study uses many different techniques to measure muscle oxygen use and look at the muscles themselves at the microscopic level. As previous studies have shown, none of our current imaging, like x-rays and CT scan and MRI, can see the problems. This is at a microscopic and cell level in the muscles.

So I am having a post-infection or Long Covid flare the last couple of days, because I pushed too far against my limits. They have not done brain studies but the suspicion is that something similar has been going on. I have been spending a lot of time contacting temp companies and doing job searches, so I am going to take a few days off from that as well. Let the brain and muscles heal.

I still think of Long Covid as immune system PTSD, where the immune system is trying to protect me from further infection, though not necessarily in a way that I like. If the immune system makes me stay home and rest, well, I shouldn’t catch anything, right? Our immune systems are as diverse and complicated as we are, so the patterns are highly variable.

My immune system can’t bamboozle me. It wants me to stay home and take it easy. I get the message. Have a wonderful day.

Cats respond to drugs differently too. Sol Duc is quiet and contemplative on catnip. Elwha, well, guess.

For the Ragtag Daily Prompt: bamboozle.
