Thank you for posting this. It's also helpful for me. I have a number of degenerative issues in my cervical spine. Where did you acquire this image from? I ask because I've been led to think that mechanical issues in the cervical spine can't cause symptoms in the head and face - I have numbness, tingling, twitching and electrical current feelings on my face and head - but it seems like your image is claiming the contrary, at least with respect to certain symptoms. My MRI showed no signal change, but in two places there was mild cervical spine compression. Thanks.
