The back of my head only hurts not serious when i touch it or rest for the night with a pillow any ideas why and it just feels uncomfortable as well?

Headache vs muscle: If it is a tender spot only, and not the whole back of your head, it is likely a pressure injury or some type of trauma (you smacked your head on the car getting in/out, for example). If it is the whole back of your head, it could be a tension headache. Go get a massage, ibuprofen, heat, etc. If it is really bothering you, you should go see your doctor for evaluation. Good luck!

Pain in the neck: It represents one of three things in most cases. Somatic dysfunction (a soft tissue problem best confirmed by a chiropractor or osteopath), arthritis in your neck with referred pain, of irritation of the nerves in the base of the skull from old whiplash or trauma.

Occipital Neuralgia: Consider getting this evaluated if not any better with rest and conservative care.
