I have tremors, not always, but sometimes I can't write or type, hold a glass or cup. I don't know if it's meds, the rsd, or I suspect the TBI also. (head trauma). (I had rsd for a long time, before the head trauma, and that's when the tremors really started).
Sometimes, I imagine it could be my sugar.
But it certainly is annoying, and Tiring! Imagine how much energy is must take, to shake like that!?
