Muscle knots in the Suboccipital muscles are located at the base of the skull, where these small but powerful muscles connect the top two cervical vertebrae to the occipital bone. These muscle knots can refer pain to the back of the head, forehead, and behind the eyes. They may also cause tension headaches, dizziness, or visual disturbances, often mimicking migraines or cervical spine issues. The pain is sometimes described as a deep, tight band or pressure that worsens with poor posture, screen time, or awkward sleeping positions.
