The suboccipital muscles are four small muscles located at the base of the skull. These muscles work to stabilize the skull on the cervical spine as well as produce movements of the head and the first two vertebrae. The suboccitpitals are often overworked from poor posture such as sitting in front of a computer for prolonged periods of time. When this happens trigger points can form in the muscles. These points will produce a deep achy pain felt through the inside of the skull into the temple and behind the eye. Trigger points in these muscles are a major cause of headaches.
