I can't decipher whether my pain is a spasm or just nerve pain. Sometimes I get what feels like an electric shock sensation or pulsation in my calf or thigh and it really doesn't feel like it's muscle related. It is ridiculously painful and feels like I'm being tazed or snapped with a thin rubber band. Every time I've read about muscle spasms being a symptom of MS, I've ruled it out because I've always imagined a charlie-horse/tightening of the muscle sort of feeling to be spasm. Like a really bad muscle cramp that is spastic?

When I mentioned it to my neuro last week, I described it as a shock sensation and he didn't mention it being a spasm, in fact based on the symptom alone he didn't even feel it was necessary to do the MRIs he did last year of my brain and spine (they were clear) over again.
