Occipital neuralgia is caused by damage to the occipital nerves, which can arise from trauma (usually concussive or cervical), physical stress on the nerve, repetitive neck contraction, flexion or extension, and/or as a result of medical complications (such as osteochondroma, a benign bone tumour).
The greater occipital nerve is a nerve of the head. It is a spinal nerve , specifically the medial branch of the dorsal primary ramus of cervical spinal nerve 2 . It arises from between the first and second cervical vertebrae , ascends, and then passes through the semispinalis muscle .
15 or more migraine (without aura) headache days per month for more than 3 months with headaches lasting at least 4–72 hours in duration; At least 2 of the following: unilateral location, pulsating quality, moderate or severe pain intensity, aggravated by or causing avoidance of, routine physical activity (walking or climbing stairs)
A headache is a pain in the head, neck or face that is often described as a sensation of pressure that varies in location, frequency and severity, according to the National Institutes of Health.
Occipital lesions can cause visual hallucinations. Lesions in the parietal-temporal-occipital association area are associated with color agnosia, movement agnosia, and agraphia. Lesions near the left occipital lobe can result in pure alexia (alexia without agraphia). Damage to the primary visual cortex, which is located on the surface of the ...
While under the trapezius, the medial branch of the posterior division of the third cervical nerve gives off a branch called the third occipital nerve (also known as the least occipital nerve), which pierces the Trapezius and ends in the skin of the lower part of the back of the head.

The perpendicular arrangement of these fibers appears to restrict dural movement toward the spinal cord. The ligamentum nuchae was found to be continuous with the posterior cervical spinal dura and the lateral portion of the occipital bone. Anatomic structures innervated by cervical nerves C1-C3 have the potential to cause headache pain ...
