What causes a headache?
Nearly 20% of headaches are cervicogenic, indicating that the cervical spine is the direct source of them (neck). Cervicogenic headaches typically only affect one side of the head, with pain starting in the neck and moving forward to the front of the head. The headache begins as sporadic attacks and eventually develops into virtually constant agony.
Neck movement or a certain neck posture may cause pain or make it worse. Pressure applied to specific areas of the neck may also cause pain. Simply being subjected to an excessive amount of stress on your neck and spine, frequently as a result of poor posture or repetitive tension of the muscles surrounding the neck, is one of the most significant causes of a cervicogenic headache.
