Trigeminal Neuralgia: When Facial Pain Strikes Without Warning
Trigeminal neuralgia is a condition that causes sudden, severe pain in the face. It is often described as an electric shock, sharp stab, or shooting pain, usually affecting one side of the face. Simple activities such as eating, talking, brushing your teeth, washing your face, or exposure to cold air can trigger an attack.
The condition affects the trigeminal nerve, which carries sensation from the face to the brain and also helps with chewing. In many cases, a nearby blood vessel presses on the nerve, causing abnormal pain signals. Depending on the affected branch, the pain may occur around the forehead and eyes, the cheek and upper jaw, or the lower jaw and chin. Because the pain can feel like a severe toothache, some patients may visit a dentist first. If the pain continues after dental treatment, a neurological evaluation may be needed.
Recognizing the Signs:
The main symptom is sudden, intense facial pain that may feel like an electric shock, stabbing sensation, or burning pain. An attack can last from a few seconds to several minutes, and some patients may experience several attacks in a single day.
As the condition becomes more frequent, patients may start avoiding activities such as eating, drinking, brushing their teeth, or talking because they are afraid of triggering another painful episode.
What Triggers the Pain?
Everyday activities can trigger an attack of trigeminal neuralgia. Eating, chewing, talking, smiling, brushing the teeth, washing the face, shaving, or lightly touching the face may cause pain. Cold air, wind, drinking, or applying makeup can also be triggers for some patients. Certain sensitive areas on the face, known as trigger points, may cause pain even with gentle touch.
Why Does It Happen?
The most common cause is a blood vessel pressing against the trigeminal nerve, which can interfere with normal nerve signals. Other possible causes include multiple sclerosis, tumors or other abnormalities affecting the nerve, and previous facial injury or surgery. In some patients, no clear cause is found.
Identifying the underlying cause helps the specialist determine the most suitable treatment.
How Is It Diagnosed?
Diagnosis usually begins with a detailed discussion about the patient's pain, including where it occurs, what triggers it, how long it lasts, and how often it happens. A neurological examination may also be performed.
An MRI (Magnetic Resonance Imaging) is often recommended to look for nerve compression and rule out other conditions, such as multiple sclerosis or a tumor. Since facial pain can also be caused by dental, sinus, jaw, or other neurological problems, an accurate diagnosis is important.
Treatment Options:
Treatment depends on the severity of the pain, its cause, MRI findings, and how the patient responds to treatment. Medication is usually the first step, while procedures or surgery may be considered when medicines do not provide enough relief.
- Medications: Carbamazepine and oxcarbazepine are commonly used to control nerve-related pain. Other medicines may be considered based on the patient's response.
- Microvascular Decompression (MVD): Moves a blood vessel away from the trigeminal nerve to relieve pressure and reduce pain.
- Radiofrequency Rhizotomy: Uses controlled heat to reduce pain signals from the affected nerve.
- Balloon Compression: Uses a small balloon to reduce the nerve's ability to transmit pain signals.
- Glycerol Rhizotomy: Uses a glycerol injection to target pain-transmitting fibers of the trigeminal nerve.
- Stereotactic Radiosurgery: Uses highly focused radiation to treat the affected nerve without open surgery.
- Neuromodulation and DBS: Deep Brain Stimulation (DBS) is an advanced neuromodulation technique. It is considered in selected patients with severe, treatment-resistant facial pain.
When Should You See a Specialist?
Recurring facial pain should not be ignored, especially when it feels like an electric shock or is triggered by simple activities. A neurologist or neurosurgeon should be consulted if the pain is severe, becoming more frequent, interfering with eating or drinking, or continuing despite dental or routine pain treatment.
Early evaluation can help identify the cause and avoid unnecessary treatments.
