Your Facial Pain: Possible Neurological Issues Explained - Neurology

Share to:

Could you please specify which symptoms you are referring to in order to determine which aspect of the nervous system may be involved?


Hello Doctor, for the past few months, I have been experiencing pain in the gums of the last tooth on the left side at the back.
Sometimes the pain radiates to my lower jaw, and at other times, it shifts to my upper jaw.
I feel like my teeth are biting the edge of my tongue and the inside of my mouth, although there is no actual injury.
Additionally, my left cheek often feels sore and painful.
I have already seen a dentist, who performed a root canal, but the pain persists.
I also consulted an ENT specialist, who found no issues.
However, the soreness in my mouth can lead to pain extending to my cheek, which then radiates to my ear.
I also experience pain in the muscles of my tongue and jaw.
Occasionally, this ear pain is accompanied by a sensation near my temple, causing a throbbing headache that extends to the top of my head.
This discomfort also leads to dryness in my mouth.
These symptoms keep recurring, and sometimes they shift to the right side of my face and ear, but they are more frequent on the left side.
(P.S.
I have a history of nasal allergies, but I'm not sure if it is related.) I would like to ask the doctor what kind of condition this might be and how I should proceed with seeking medical attention.
Thank you.

Dear Ms.
Lee,
You mentioned that "the acidic pain in the mouth can extend to the cheeks and then to the ears, and it can also radiate to the muscles of the tongue and the upper and lower jaws," which suggests trigeminal neuralgia.
The diagnostic criteria for trigeminal neuralgia are as follows:
- At least three attacks
- Pain occurring in one or more branches of the trigeminal nerve
- At least three of the following characteristics of the pain:
- Duration from a fraction of a second to two minutes, occurring in a periodic or paroxysmal manner
- Severe intensity of pain
- Electric shock-like, burning, or sharp pain
- Three or more trigger points on the face
- No other obvious clinical neurological deficits
Unlike other types of pain, anti-inflammatory and analgesic medications are not very effective for trigeminal neuralgia.
The treatment for trigeminal neuralgia primarily involves anticonvulsant medications, with the most commonly used being Carbamazepine (Tegretol), Oxcarbazepine (Trileptal), and Lamotrigine.
These anticonvulsants have been proven to be effective treatments, making medication therapy often the first choice.
I recommend that you ask your dentist for a referral to a regional hospital's oral surgery department for a second opinion.
(Patients with a referral will be prioritized for appointments at the referral desk.) If the oral surgeon rules out any structural abnormalities, they will typically refer you to the hospital's neurology department.
You may also consult with a neurologist for discussion and treatment.
Thank you for your inquiry, and feel free to reach out for further discussion on related issues!
Wishing you good health, peace, and joy.
Dr.

More Info


It sounds like you are experiencing a complex array of symptoms that could be related to several underlying issues, particularly involving your dental health, neurological function, and possibly even your allergies. Let's break down your symptoms and explore potential causes and recommendations for further evaluation.


Symptoms Overview
You mentioned experiencing:
- Pain in the gums of a specific tooth, which sometimes radiates to the upper and lower jaw.

- Facial pain, particularly in the left cheek, which can extend to the ear and even the temple area.

- Occasional pain that shifts to the right side of your face.

- Discomfort in the tongue and oral muscles, with sensations of dryness.

- A history of dental procedures, including nerve treatment, which did not alleviate the pain.

- Allergies, particularly nasal, which may contribute to your symptoms.


Possible Causes
1. Dental Issues: Since you've already seen a dentist and undergone nerve treatment, it's essential to consider that there may still be underlying dental issues, such as:
- Residual Infection: Sometimes, infections can persist even after treatment. A follow-up with your dentist or an endodontist (root canal specialist) might be necessary to ensure that there are no lingering issues.

- Temporomandibular Joint (TMJ) Disorder: TMJ disorders can cause pain in the jaw, face, and even the ears. Symptoms often include jaw clicking, difficulty chewing, and facial pain that can mimic dental pain.

2. Neurological Factors: The way your pain radiates could suggest a neurological component:
- Trigeminal Neuralgia: This condition can cause severe facial pain that feels like electric shocks. It often affects one side of the face and can be triggered by touch or movement.

- Nerve Compression or Irritation: Conditions like herniated discs in the cervical spine can lead to nerve compression, resulting in referred pain to the face.

3. Sinus Issues: Given your history of nasal allergies, sinusitis could be a contributing factor:
- Sinus Infection: Inflammation or infection of the sinuses can cause facial pain, especially around the cheeks and forehead, and can also lead to ear pain.

4. Allergies: Allergic reactions can lead to inflammation in the nasal passages and sinuses, which may exacerbate facial pain and discomfort.


Recommendations
1. Follow-Up with Dental Care: Since dental issues can often be complex, consider getting a second opinion from another dentist or a specialist in orofacial pain. They may conduct imaging studies (like X-rays or a CT scan) to rule out any hidden dental problems.

2. Consult a Neurologist: Given the neurological symptoms and the nature of your pain, a neurologist can evaluate you for conditions like trigeminal neuralgia or other nerve-related issues. They may recommend imaging studies like an MRI to assess for any abnormalities.

3. ENT Evaluation: Since you have a history of nasal allergies, an evaluation by an ear, nose, and throat (ENT) specialist could help determine if sinus issues are contributing to your symptoms.

4. Allergy Management: If allergies are a significant factor, managing them with antihistamines or nasal corticosteroids may help alleviate some of the discomfort.

5. Pain Management: Discuss pain management options with your healthcare provider. This could include medications, physical therapy, or other interventions to help manage your symptoms.


Conclusion
Your symptoms are multifaceted and could stem from various sources, including dental, neurological, and allergic factors. It is crucial to pursue a thorough evaluation with the appropriate specialists to pinpoint the exact cause of your discomfort and develop an effective treatment plan. Don't hesitate to seek further opinions and advocate for your health until you find the relief you need.
