Have you ever noticed the way youa re sleeping when this happens. Do you move your neck a certain way and it starts? Try to write down exactly what happens, how long it lasts, what you did and feel may have brought it on..You may need to see an ENT first and then a Neurologist depending on what you can document..I hope this helps some..I go numb when my neck moves certain ways-it has taken months but finally am at a place where docs are agreeing it's my neck..Best o fluck hon..DOn't give up keep tyring to get answers..
