Despite a boat load of meds, I still spasm and twitch.

Among my favourite spasms are the one that closes my throat so I can't breath for a few seconds and the one that makes my hand fly open (bye, bye coffee cup.) It's like being tasered a hundred times a day.

Additionally, do you guys have the the sensation of nerve pulses all over your body and/or shaking hands?

Anyway, as I also have spinal cord damage, it's hard to say if the source is brain or neck (probably both). Either way, they're no fun.
