Facial nerve paralysis

Hello, doctor.
On March 14th, I suddenly felt pain in the right side of my neck, which didn't feel like a muscle strain but rather like nerve pain.
However, it improved by the evening.
On the morning of March 15th, the pain returned and lasted all day until just before bedtime.
On the morning of March 16th, I woke up with a vague pain again, and then I noticed that the right side of my face seemed to have facial nerve paralysis.
I cannot fully close my right eye, and when I smile, the right side does not lift completely.
I would like to know if this is simply facial nerve paralysis or if it is related to the nerve in my right neck.
Could the neck nerve pain be a precursor to the paralysis? Can I recover by just taking medication? I heard from a doctor that the golden period for recovery is within a week.
In my case, would this be considered the second day or the third day? Thank you for your response, doctor! Thank you!

Hello: Your symptoms indicate peripheral facial nerve paralysis, primarily affecting the seventh cranial nerve (if it were due to cervical nerve compression, it would not affect the face).
Clinically, symptoms may include pain behind the ear 1-2 days prior to the onset.
There may be sensations of numbness or stiffness in the face.
Due to the inability to close the eyelid, tearing may occur.
Sometimes, patients may notice an increased sensitivity to sound due to a decrease in the stapedius reflex, as well as a reduced sense of taste on the tip of the tongue.
Typically, the impact on facial muscles is quite extensive.
Aside from corticosteroids, there is insufficient evidence to support the effectiveness of other treatment methods.
This can increase the chances of successful rehabilitation from 60% to over 70%.
Treatment usually lasts 1-2 weeks.
Please receive corticosteroid treatment during the acute phase.
Other treatment options include medications such as vitamins and agents to improve blood circulation, as well as electrical stimulation, acupuncture, massage, low-level laser therapy, infrared irradiation, shortwave therapy, and facial muscle exercise.
After the acute phase, there are almost no medications that are definitively helpful, and patients are advised to take vitamin B complex as an adjunct.
Approximately 10 to 20% of cases of facial nerve paralysis do not fully recover.
The most common clinical presentation is Bell's palsy, which is often of unknown origin or due to viral infections, leading to impaired blood circulation that nourishes the facial nerve, resulting in dysfunction and subsequent facial muscle paralysis.
It is recommended that you consult a neurologist for discussion and treatment.
Wishing you good health, peace, and joy.

More Info

Facial nerve palsy, often referred to as Bell's palsy when idiopathic, can be a distressing condition that affects a person's facial muscles, leading to weakness or paralysis on one side of the face. Understanding the causes, symptoms, and treatment options is crucial for effective management and recovery.

Causes of Facial Nerve Palsy
Facial nerve palsy can arise from various factors, including:
1. Viral Infections: The most common cause is viral infections, particularly the herpes simplex virus, which can lead to inflammation of the facial nerve.

2. Trauma: Physical injury to the facial nerve can result from accidents or surgical procedures.

3. Neurological Conditions: Conditions such as multiple sclerosis or tumors can affect the facial nerve.

4. Idiopathic Causes: In many cases, the exact cause remains unknown, which is often classified as Bell's palsy.

In your case, the onset of neck pain followed by facial weakness raises the question of whether the neck pain is related to the facial nerve issues. While it is possible for cervical spine problems to affect nerve function, the sudden onset of facial weakness is more commonly associated with direct facial nerve involvement rather than referred pain from the neck.

Symptoms of Facial Nerve Palsy
The symptoms of facial nerve palsy can vary but typically include:
- Facial Weakness: Inability to smile, close the eye, or raise the eyebrow on the affected side.

- Loss of Facial Expression: The face may appear droopy or asymmetrical.

- Altered Taste Sensation: Changes in taste perception on the front two-thirds of the tongue.

- Increased Sensitivity to Sound: Hyperacusis, where sounds may seem louder in the affected ear.

- Tearing and Salivation Issues: Difficulty in producing tears or saliva.

Given your symptoms of right-sided facial weakness and inability to close the right eye, it is likely that you are experiencing facial nerve palsy.

Treatment Options
The treatment for facial nerve palsy typically includes:
1. Medications: Corticosteroids, such as prednisone, are often prescribed to reduce inflammation and swelling of the facial nerve. The effectiveness of these medications is highest when started within the first few days of symptom onset.

2. Physical Therapy: Facial exercises can help maintain muscle tone and improve facial function. A physical therapist can guide you through specific exercises tailored to your condition.

3. Pain Management: If you experience pain, analgesics or anti-inflammatory medications may be recommended.

4. Eye Care: If you cannot close your eye completely, using lubricating eye drops or an eye patch at night can help protect the eye from dryness and injury.

5. Alternative Therapies: Some patients find relief through acupuncture or electrical stimulation, although evidence for these treatments is less robust.

Prognosis and Recovery
The "golden period" for treatment effectiveness is indeed within the first week of symptom onset. Since you mentioned that your symptoms began on March 16, you are still within this critical timeframe. Most patients experience significant recovery within three to six months, although some may have residual weakness or other symptoms.

It's essential to follow up with a healthcare provider, preferably a neurologist, who can assess your condition and recommend a tailored treatment plan. Early intervention can significantly improve outcomes and reduce the risk of long-term complications.

In summary, facial nerve palsy can be a challenging condition, but with appropriate treatment and care, many individuals can achieve a full or near-full recovery. If you have further concerns or your symptoms worsen, do not hesitate to seek medical attention promptly.
