What causes painful muscle spasm in back of head?

A doctor has provided 1 answer

Several things: It could be due to trauma, like whiplash injuries or heavy work. Neck degenerative arthritis can do this. Irritation of some of the small nerves to the neck muscles are a possibility. If it is not getting better, talk to your primary doctor or a specialist who takes care of neck problems.
