I'm not really sure where to post this as it could be anything. Has anyone out there had the "electric pricklys"? I don't know how else to describe it other than to say it seems to begin at the back of my skull and go through my body in a wave leaving every single nerve ending on my skin and just under the surface feeling like I'm recieving some kind of electrial shock. It usually lasts for a minute or less, but I find I'm getting it more frequently and was hoping I'm not the only one and there's something I can do. I'd be grateful for any input.
