Na - Seriously, I get it on and off, but in addition to the feeling of something crawled through my hair, I get a serious pinching, burning and itching on the inside of my arms on and off. I could rip my skin
off it drives me so crazy. There is nothing there, no spots, no bumps
, nothing. Can last days, or hours - it varies so much.
I would say since there is nothing there you can see either, it's more than likely parethesias caused by the damage from your MS.
