Electric Shock Feelings?

Anyone else experience what feels like an electric shock going from one arm across to the other? Got SPMS, but not experienced this sensation before.

@n3tm4n , this may be a manifestation of L'Hermittes Sign :- https://www.mstrust.org.uk/a-z/lhermittes-sign

I have SPMS too and regularly experience electric shocks in my lower back and shoulders. Thankfully they are very brief shocks, bot they do come in groups of 3 - 6 rapid fire bursts.
