Chronic head ache

Occipital neuralgia refers to pain in the posterior head occipital nerve and small occipital nerve. The sensation of the posterior occipital region and the neck is innervated by the first, second, and third pairs of cervical nerves. The posterior branch of the second cervical nerve constitutes the greater occipital nerve. Deep tissue is located in the middle of the line connecting the mastoid and the midpoint behind the first cervical spine. Simple, distributed in the back of the occipital region is equivalent to the outer ear canal on both sides after the head and neck line. The anterior branch of the third cervical nerve constitutes the occipital nerve and the auricular nerve. The small occipital nerve is mainly distributed on the skin above the auricle and outside the occipital, and the large auricular nerve is mainly distributed on the front and back of the lower auricle, on the surface of the parotid gland, and on the angle of the mandible. When the three nerves are involved, it can cause pain in the posterior occipital and neck, and often appears in the form of neuralgia. The posterior root of the first cervical nerve is generally very small, so the posterior occipital and neck pain caused by spinal nerve disease of the upper cervical segment are collectively referred to as occipital neuralgia. Frequent occipital pain is mostly related to inadequate blood supply to the vertebrobasilar artery, which is mainly caused by cervical spondylosis.
