For patients with trigeminal neuralgia, when they frequently experience bouts of pain, most do not have significant facial swelling. The pain typically occurs distinctly in the areas distributed by the trigeminal nerve roots, often starting and stopping suddenly, and each episode may last from a few seconds to several minutes. Due to repeated pain, facial muscle atrophy may occur, but generally, there is no swelling of the face. For treating trigeminal neuralgia, surgery is commonly used. Microvascular decompression surgery is often recommended to help improve symptoms and can even achieve a clinical cure.
