Trigeminal neuralgia?


The patient has recently experienced pain in the upper right teeth, described as a dull ache, and visited a dentist.
The dentist indicated that the teeth themselves are fine, but there is mild inflammation of the gums.
However, the patient has noticed that sometimes when drinking or swallowing, there is a sudden sharp pain or stabbing sensation inside the teeth.
This pain seems to occur when bending down for an extended period and then suddenly looking up, but attempts to replicate this action or swallow saliva do not trigger discomfort.
This has been ongoing for about a week, and the symptoms have improved.
The patient also has a history of cervical disc herniation with nerve compression at levels C3-4-5-6, with symptoms that fluctuate.
The patient consulted the dentist about the possibility of trigeminal neuralgia, but the dentist indicated that it does not seem likely.
The patient is seeking clarification on whether their symptoms could be related to trigeminal neuralgia and if they might be caused by the cervical condition.

Hello: Your symptoms are very similar to trigeminal neuralgia, but a period of observation is needed.
According to the International Classification of Headache Disorders, Third Edition (ICHD-3), the diagnostic criteria for trigeminal neuralgia are as follows:
- At least three episodes
- Pain occurs in one or more branches of the trigeminal nerve
- At least three of the following pain characteristics must be met:
o Duration of a few seconds to two minutes, with periodic, paroxysmal attacks
o Severe pain intensity
o Electric shock-like, burning, or sharp pain
o More than three trigger points on the face
- No other obvious clinical neurological deficits
Regarding cervical nerve disorders, since the primary distribution is from the forehead to the back of the neck, it is recommended that you consult a neurologist for discussion and treatment.
Wishing you good health and peace.
Dr.
Tao, Neurology, cares about you.

More Info


Trigeminal neuralgia (TN) is a chronic pain condition that affects the trigeminal nerve, which is responsible for sensation in the face and motor functions such as biting and chewing. It is characterized by episodes of severe, shooting pain that can be triggered by everyday activities like eating, drinking, or even touching the face. The pain is often described as electric shock-like and can be debilitating, significantly impacting the quality of life.

In your case, the symptoms you describe—such as the sharp, sudden pain in the upper right area of your mouth, particularly when swallowing or moving your head—could potentially be related to trigeminal neuralgia, especially given the nature of the pain. However, it is important to note that TN typically presents with more intense and sudden episodes of pain, often triggered by stimuli that would not normally cause discomfort. The fact that your symptoms have improved over the week and that you do not consistently experience pain with repeated actions may suggest that your condition could be different.

Your history of cervical disc herniation (C3-4-5-6) is also relevant. Cervical spine issues can lead to nerve compression, which may cause referred pain or neurological symptoms in the upper body, including the face. It is possible that the nerve compression from your cervical spine could be contributing to your symptoms. This is known as referred pain, where pain is perceived in an area different from its source.
Given that your dentist has indicated that your teeth are healthy and that the issue seems to stem from the gums, it may be worthwhile to explore the possibility of a nerve-related issue further. A consultation with a neurologist would be beneficial to assess whether your symptoms align with trigeminal neuralgia or if they are related to your cervical spine condition. They may recommend imaging studies, such as an MRI, to evaluate the trigeminal nerve and the cervical spine for any abnormalities.

In terms of management, if trigeminal neuralgia is diagnosed, treatment options typically include medications such as carbamazepine or gabapentin, which are effective in managing nerve pain. In some cases, surgical interventions may be considered if medication does not provide relief. For cervical spine issues, physical therapy, pain management strategies, or even surgical options may be necessary depending on the severity of the nerve compression.

It's crucial to monitor your symptoms and seek a comprehensive evaluation from a healthcare professional who specializes in neurology. They can provide a more accurate diagnosis and tailor a treatment plan that addresses both your facial pain and any underlying cervical spine issues. Remember, early intervention can often lead to better outcomes, so don't hesitate to pursue further medical advice.
