Facial issues


Hello Dr.
Jiang, last November, I experienced intermittent twitching in my lower left lip for almost a month.
I went to a neurologist for an examination, and tests for trigeminal nerve and thyroid function were normal, with no signs of inflammation.
The doctor suggested that it was likely due to stress and anxiety causing abnormal nerve discharges.
After adjusting my schedule and ensuring I get 8 hours of sleep each night, I did recover.
However, since early February, I have occasionally felt twitching in the muscles of my right cheek, about 2-3 times a day; my right jaw feels tight (or numb) for about a second, approximately 7-8 times a day, but not every day.
Sometimes it occurs for two consecutive days, then it may not happen the next day.
Therefore, I would like to ask Dr.
Jiang if this condition could be a precursor to facial nerve paralysis, or if it is similar to the previous issue of abnormal nerve discharges? Should I go back to the neurologist for further examination? Thank you.

Hello: The clinical manifestation of facial nerve paralysis is muscle weakness.
If accompanied by other sensory symptoms, one should consider the possibility of trigeminal nerve involvement.
The most common cause of trigeminal nerve pathology is compression by vascular structures as the trigeminal nerve exits the brainstem, typically affecting patients around the age of 50.
Other causes such as vestibular schwannoma, meningioma, multiple sclerosis, and herpes zoster can amplify normal sensory signals like touch and temperature into pain signals, leading to symptoms of trigeminal neuralgia.
If symptoms persist, it is advisable to consult a neurologist for discussion and treatment.
Wishing you good health and peace.
Sincerely, Taoyuan Medical Center, Neurology Department.

More Info


Understanding facial nerve issues, particularly facial nerve disorders such as Bell's palsy or facial nerve paralysis, is crucial for recognizing symptoms and knowing when to seek medical help. Based on your description, it seems you have experienced intermittent muscle twitches and sensations in your face, which can be concerning.
Facial nerve disorders can manifest in various ways. Common symptoms include:
1. Facial Weakness or Paralysis: This may present as drooping on one side of the face, making it difficult to smile or close the eye on that side.

2. Muscle Twitches or Spasms: These can occur in the facial muscles and may be mistaken for more serious conditions.

3. Altered Sensation: Some individuals report numbness or tingling in the face.

4. Pain or Discomfort: This can include pain around the jaw or behind the ear.

5. Changes in Taste: Some may experience altered taste sensations, particularly if the facial nerve is affected.

6. Tearing or Salivation Issues: This can manifest as excessive tearing or dry eyes, as well as changes in saliva production.

In your case, the intermittent muscle twitches and sensations you describe could be related to stress and anxiety, as you mentioned that previous symptoms were attributed to these factors. Stress can lead to increased muscle tension and involuntary muscle contractions, which might explain the symptoms you are experiencing. However, it is essential to differentiate between benign muscle twitches and more serious conditions like facial nerve disorders.

When to seek medical help:
1. Persistent Symptoms: If your symptoms persist or worsen, it is advisable to consult a healthcare professional. This is particularly important if you experience new symptoms such as facial drooping, difficulty closing your eye, or changes in vision.

2. Acute Onset of Symptoms: If you suddenly develop weakness or paralysis in your face, seek immediate medical attention to rule out conditions like stroke.

3. Associated Symptoms: If you experience other neurological symptoms, such as severe headaches, dizziness, or changes in consciousness, you should seek medical care promptly.

4. Concern for Underlying Conditions: If there is a history of neurological issues or if you have had previous episodes of facial nerve problems, it is wise to have a thorough evaluation.

In your situation, since you have already had a neurological evaluation that ruled out significant issues, it may be reasonable to monitor your symptoms, especially if they are infrequent and not accompanied by other concerning signs. However, if you notice any changes or if the symptoms become more frequent or severe, returning to a neurologist for further evaluation would be prudent.

In terms of treatment, managing stress through lifestyle changes, such as regular exercise, adequate sleep, and relaxation techniques, can be beneficial. If anxiety is a significant factor, cognitive-behavioral therapy (CBT) or other forms of counseling may also help.

In conclusion, while your symptoms may be benign and related to stress, it is essential to remain vigilant. If you have any doubts or if your symptoms change, do not hesitate to seek further medical advice. Early intervention can be crucial in managing any potential underlying conditions effectively.
