Understanding Trigeminal Neuralgia
Trigeminal neuralgia (TN) is a chronic neurological condition that causes sudden, severe facial pain. This guide is a starting point for anyone trying to make sense of a new diagnosis, an unexplained pain, or a loved one's experience.
What is trigeminal neuralgia?
TN affects the trigeminal nerve — the largest cranial nerve, responsible for sensation in the face. When it misfires, patients often describe pain as electric shocks, stabbing, or burning. Episodes can be brief but are some of the most intense pain known to medicine.
What does TN pain feel like?
Symptoms vary, but common patterns include sudden one-sided facial pain, pain triggered by light touch, chewing, talking, brushing teeth, or cold air, and episodes that come in clusters separated by pain-free periods. Many patients describe the experience in their own words in our patient stories.
What causes trigeminal neuralgia?
The most common cause is a blood vessel pressing against the trigeminal nerve where it exits the brainstem. Less commonly, TN can be linked to multiple sclerosis, tumors, or facial injury. In some cases no specific cause is identified — this is sometimes called idiopathic TN.
How is TN diagnosed?
Diagnosis is primarily clinical — based on the pattern of pain a patient describes — supported by an MRI to rule out other causes. Because TN symptoms overlap with dental, sinus, and ear conditions, many patients spend months or years searching for the right diagnosis. Read about the conditions most often mistaken for TN, and our family's two-year diagnosis journey.
What about treatment?
TN is usually managed first with medication (such as carbamazepine or oxcarbazepine). When medication stops working or side effects become intolerable, several procedures can help. Our surgery hub compares MVD, Gamma Knife, radiofrequency ablation, and balloon compression.
