Why most chronic headaches start in the neck
The top three cervical vertebrae share nerve pathways with the trigeminal nerve — the same nerve that carries pain signals from your face, sinuses, and the front of your head. When C1 through C3 lose mobility or the suboccipital muscles stay in chronic guard, your nervous system reads it as a frontal, sinus, or 'around the eye' headache. The pain shows up in front; the cause is in the back.
