Sounds to me like you need to see a Doctor for a possible prescription to help you out. Only he/she can make a proper diagnosis and see what will work best for you. This site even has an over the counter drug that might help. See your Doctor !
It could be starting in your neck.
Do this, take the pole off of a plunger,
with both hands on either end and,
place it on the back part of your neck
and, pull and press downward starting
at one side then move slowly to the other side.
With out a lot of force.
