Thank you for the response.
I mentioned this to my GP a couple years ago when I last noticed it. She said its normal to get little sensations , especially with anxiety. If they get worse, or I develop other things to check back with her.
I'm freaking myself out going on MS sights all the time, trying to make sense of stuff. Maybe making myself psychosomatic and terrified!
The other way to describe this feeling is like very mild little sparks that last 1 second, somewhere on your leg or arm.
