The causes of upper lip twitching may be facial nerve palsy, Parkinson’s disease and cerebral infarction.
1. Facial nerve palsy: If the facial neurons distributed in the upper lip are damaged, resulting in abnormal nerve function, the upper lip may keep twitching.
2. Parkinson’s disease: due to the degenerative disease of the nervous system of the elderly, there may be clinical manifestations such as resting tremor, muscle tonus and motor retardation, which may result in the phenomenon of constant twitching of the upper lip.
3. Cerebral infarction: If acute ischemia of blood vessels in the brain causes cerebral vasospasm, when the blood vessels distributed around the upper lip spasm, it can lead to upper lip twitching all the time.
If your upper lip keeps twitching, you must go to the hospital in time to find out the cause of the disease and actively cooperate with the professional doctor’s treatment.
