Lip twitching may be caused by physiological factors, such as excessive fatigue, but it may also be caused by facial muscle spasm, Parkinson’s disease and other disease-related factors.
1. Physiological factors: over-fatigue or prolonged stress can easily trigger nervous tension, which leads to lip twitching. Most of them do not need any special treatment, and the symptoms can be improved by themselves after taking a good rest and relieving stress.
2. Facial muscle spasm: it is usually caused by the blood vessels in the bridge cerebellar angle area compressing the facial nerve root, but it may also be caused by occupational lesions, such as tumors, inflammation, cysts, etc. After the onset of facial muscle spasm, the patient’s facial muscles on one side of the face may be affected.
After the onset of the disease, the patient’s facial muscles on one side will appear paroxysmal, rhythmic twitching, the onset of the initial period, the orbicularis oculi muscle will appear intermittent twitching, and then, it can appear in the orbicularis oculi muscle and facial expression muscle, the corner of the mouth muscle is the most obvious. It can be accompanied by headache, deafness and other discomforts.
3. Parkinson’s disease: mostly occurs in middle-aged and old people, mainly due to the degenerative death of nigrostriatal dopaminergic neurons, and the cause of the degenerative death of nigrostriatal dopaminergic neurons is still unclear, and is mostly related to heredity, the environment, and neurological aging, which leads to lip twitching, muscle rigidity, slow movements, dementia and so on.
In addition, there are many other causes that can cause lip twitching, and patients are advised to go to the hospital in time to identify the cause of the disease and receive treatment as soon as possible.
