I have mild facial numbness all the time. It was one of the first severe symtoms that drove me to the doc when I was starting to crash and burn with fibro. I also have numbness on my arms and down the back of my legs. The doc did the usual MRIs to check for MS...and didn't see anything. Today I woke with numbness on the tip of my tongue and it hasn't gone away all day. Has anyone else had their numbness spread like this? Why would this happen? It isn't so bad that I have bit my tongue but, if it gets any worse, that will probably happen. I have been ill for at least 7 years (diagnosed).
