I had weird muscle issues. Fasciculations. Something usually dismissed out of hand. But with the severity and some other stuff, I presented a bit like MS, ALS, restless leg syndrome, and some other stuff I now forget. Did tests, drugs, therapies -- nothing conclusive, nothing helped.

Eventually, finally, got some MRIs done. Was immediately obvious my nerves were impinged. Which led to surgeries.

Happily, surgery resolved most of my anxiety symptoms (which had also been treatment resistant). Of which my care providers are very skeptical. Specifically, that my physical sensation of anxiety, like clinching, induced my emotional state. Maybe not. But lacking a better theory, I'm preceding with the info that I have.
