hi there nooper welcome to the forum, sorry to hear about your troubles.
you might wish to look into your serum magnesium level. magnesium tends to be low in ms patients. low mag affects different people in different ways. it has over 300 jobs to do in your body, so there are a lot of different seemingly unrelated things that can go wrong, but all having a magnesium issue in the mix somewhere.

Carpopedal spasm (tetany)
Muscle faciculations and tremors
Hemiparesis and aphasia
Torsade de pointes
if you decide to get tested, ensure your serum level is at least 0.90 mmol/L. the 'normal' range is 0.70-1.10 mmol/L (too wide by half) so make sure you get the number and don't let them tell you your result is 'normal' - you could be in the 0.70-0.89 part of the 'normal' range, along with a lot of other sick people.
hope you feel better soon!
