Spasticity

So, here I am - physically and mentally, like, squeezed and I'm wondering, like, when is it that I have to stop pretending that it isn't and actually face up to the fact that my left thumb is going spastic on me, a little bit more every day, but definitely spastic?

There's a pretty question.

Thing is I have never had anything go spastic on me yet. So to acknowledge the thumb's spasticity is to acknowledge a whole new different symptom. And I'm not sure I want to do that before finishing off some work I am working on, and stuff. Got to look into it because I can't remember if spasticity is caused in the brain or in the spinal column (like the various exciting forms of paraesthesia I live with).

But I won't look it up because that would mean taking my head out of the sand.
