Hi, yes I’ve had this on and off for years. Actually years before I had MS symptoms so don’t think they’re related (but who knows).
One trick I’ve taught myself over the years. Try and move just one finger. That’s usually enough to jolt you out of it. Just concentrate on one finger and moving it. Over time it gets easier.
It is a very distressing feeling and you have my sympathy, but I will say that I’m more used to it now and it doesn’t frighten me nearly as much as it used to.
I often get it when on any kind of drug… the last time I was getting it regularly was when I was on Gabapentin.
I’ve also noticed that I get it more freqently at times when I’m stressed out so I think there’s a link there as well. Just seems that some people are prone to it.
