Pain in the back of the head when chewing and swallowing may be related to glossopharyngeal neuralgia, occipital neuralgia and so on. 1. Hypoglossal neuralgia: after 40 years of age, both men and women can be involved. The pain occurs in the posterior 1/3 of the tongue and tonsils on one side, radiating to the pharynx, soft palate, eustachian tube, and the ear canal on the same side. It is a sharp, knife-like pain that passes in seconds; it recurs after intervals. It can be induced by swallowing food, speaking, and mouth and jaw activities. 2. Occipital neuralgia: It refers to the disease with the main clinical manifestation of radiating pain within the distribution range of the occipital nerve (top of the occiput) due to strain injury, inflammatory stimulation and other reasons leading to local soft tissue exudation, adhesion and spasm, stimulation, card pressure or pulling the occipital nerve. It may be triggered by head movements such as chewing and swallowing. Pain in the back of the head when chewing and swallowing may also have other causes, it is recommended to consult a doctor in time to identify the cause of the disease and then actively treat it, so as not to delay the condition.
