What causes one spot of numbness on the tongue?
I have been having severe upper back pain and muscle tightness. I woke up last week with a numb spot on the right side of my tongue. I immediately went to the Dr. Who promptly ordered an MRI which was completely normal! A week later, I still have the numbness along with very tight neck muscles and a weird numb sensation in my throat. My Dr. Says that he feels it is a facial nerve. I think maybe I am still concerned because of all the comments on stroke but the Dr. Said something would have shown up on the MRI. Any suggestions of what this could be?
