There are more causes of facial pain, which may be related to trigeminal neuralgia, mumps and facial shingles. 1. Trigeminal neuralgia: local demyelination of the trigeminal nerve produces ectopic impulses, and the synapses of adjacent axonal fibers produce short circuits, causing discharge-like pain throughout the face. The time of pain is usually not fixed, but once it occurs the pain is severe and unbearable. 2. Mumps: generally caused by parotid virus infection, resulting in inflammation of the parotid tissue, causing obvious redness, swelling, heat and pain in the parotid position. 3. Facial herpes zoster: It may be caused by a sudden decrease in immunity or overwork, resulting in facial infection with herpes virus, which can cause pain and even facial paralysis when it invades the facial nerve. When facial pain occurs, it is recommended to consult a doctor in time, follow the doctor’s instructions for further examination, clarify the cause with the help of the doctor, and carry out targeted treatment or therapy.
