I get this but only after I’ve done physical activity. By which I mean ANY physical activity. I rocked a baby in my lap for 5 minutes and my abs burned like I’d been doing crunches for an hour. And they were sore for 3 days.
You don’t realize how much muscle you use in everyday activities until they get weak and using them at all is a workout. So maybe you’ve done just a little more work before this happens?
Obviously it’s worse while herxing- all my muscles get weak when I’m on tough treatment.
Lyme, Babesia, Bartonella. Symptoms began 5/2016, didn't start treatment until 9/2016. Slow but steady recovery.
