In patients with facial paralysis, lip throbbing is considered to be due to muscle strength recovery as well as facial muscle twitching.
1. Recovery of muscle strength: Patients with facial paralysis may experience lip throbbing about one week after the onset of the disease, which may be due to the process of muscle strength recovery. After the acute phase, the muscle function of the paralyzed side may recover gradually. When the nerve function gradually recovers, poor motor control may occur, resulting in lip muscle throbbing.
2. Facial muscle spasm: the patient’s local muscle nerve injury, resulting in the local muscle nerves innervating the movement of the corners of the mouth, the local nerve excitability increases, resulting in the symptoms of spontaneous corner of the mouth jumping.
It is recommended that patients with facial paralysis who have throbbing lips should consult a doctor in time and be treated under the guidance of a professional doctor to avoid delaying the condition.
