The common causes of facial muscle throbbing include physiological factors, facial muscle spasm, facial neuritis, etc. 1. Physiological factors: due to prolonged exposure to cold or prolonged high mental tension, facial muscles spasm, resulting in facial muscle throbbing, often transient. 2. Facial muscle spasm: the facial nerve pathway is mechanically stimulated or compressed, resulting in ectopic excitation of the facial nerve, resulting in facial muscle throbbing. 3. Facial neuritis: the facial nerve is not well restored, so the myelin sheath recovery is incomplete, and the conduction of the facial nerve is affected, resulting in facial muscle throbbing. There may be other reasons for facial muscle throbbing, so it is recommended to go to the hospital in time, improve the examination, clarify the cause of the disease, and carry out standardized treatment under the guidance of the doctor.
