Main Causes Of Trigeminal Neuralgia
Trigeminal neuralgia is most often caused by compression of the trigeminal nerve, usually by a blood vessel pressing against it near the brainstem. This pressure can damage the protective covering of the nerve, leading to sudden, severe facial pain. Other potential causes include multiple sclerosis or, rarely, tumors that affect the nerve. Identifying the underlying cause is important for choosing the most effective treatment.
