I think of three things with what you described....
1) aura's which is a pre sign of a migraine or headache basically
3) neck misaligned and when you pop it back in place the sensation goes away
However, we are not doctors. I have medical training, but I am going on MY personal experience. I've had that with migraines (aura) as well as my neck being out of alignment.
