Sometime I have tingling that starts in the fingertips of my right hand and works its way up to my face, tongue, lips, and everything else in between. I finally went to the doc. To see if they had anything to say about it. At the time I am awaiting an mri and as of now all they can tell me is what they think it may be; which is a tia or a spasm of an artery in the brain that momentarily cuts of blood flow to certain parts of the body. But that is all I know for now.
