Did you know that certain headaches come from your neck? They are called cervicogenic headaches. Cervicogenic literally means produced by the neck; cervico- means neck and -genic means produced by. Abnormal Cervical spine alignment and posture has a negative impact on neck movement, shock absorption, and spine stability leading to degeneration of the Cervical spine. Neck muscles have to continuously work harder to move and stabilize the head and neck which increases tension and stress on the head and neck. And, as these neck muscles work harder for longer periods of time, they become weaker which requires them to work even harder. It should come as no surprise that abnormal Cervical spine alignment and posture has been linked to cervicogenic headaches.
