Causes and Diagnoses of Trigeminal Neuralgia
Trigeminal neuralgia is usually caused by a blood vessel pressing against the trigeminal nerve. In some cases, it can be caused by multiple sclerosis or, more rarely, a tumor.
To diagnose trigeminal neuralgia, your physician will typically take your health history and do a physical exam. Giving your healthcare provider details about the pain, such as where and when the pain happens, will help with making a diagnosis. Imaging tests may be used to try to rule out other causes of pain.
Tests may include:
- Blood tests, including tests for blood sugar and Lyme disease
- Computed tomography (CT) scan
- Magnetic resonance imaging (MRI)
- Neurological exam to check vision, hearing, coordination, balance and reflexes
- Physical exam
- Positron emission tomography (PET) scan
