Trigeminal neuralgia is a nerve disorder that causes sudden and intense bouts of facial pain. People suffering from trigeminal neuralgia may experience sharp sensations along the side of their face, which can be triggered by everyday activities, like brushing their teeth or applying makeup.\nThe trigeminal nerve carries feeling from your face to your brain. When the nerve is disrupted, often because a blood vessel is pressing against it, the nerve can malfunction and send stinging, shock-like pain along the side of the face.\nHow Trigeminal Neuralgia Affects People\nThere are three types of trigeminal neuralgia: typical, atypical, and transitional.\nWant to learn more?

Typical trigeminal neuralgia is triggered by activities that stimulate the face, such as:\n\nApplying makeup\nBrushing teeth\nDrinking a cold beverage or eating\nShaving\nSmiling\nTouching the face\n\nAtypical trigeminal neuralgia, meanwhile, causes pain that is often burning or aching in nature. This condition has no known triggers, so it can occur without warning. The third category, transitional trigeminal neuralgia, is a combination of the two: It may or may not occur following stimulation of the face.\nCauses and Symptoms of Trigeminal Neuralgia\nThe disorder occurs when pressure is applied to the trigeminal nerve, causing it to malfunction. Trigeminal neuralgia can occur naturally as part of the aging process or as a result of other disorders that damage the covering that protects certain nerves, such as multiple sclerosis.\nGeneral symptoms of trigeminal neuralgia include:\n\nSpontaneous instances of sharp pain, lasting a few seconds to a few minutes.\nConstant aching in the jaw.\nPain on one side of the face. In rare cases, trigeminal neuralgia may cause pain on both sides of the face.\n\nRELATED:\u00a0\u201cBrilliant Surgical Skill:\u201d One Woman\u2019s Recovery from Nerve Pain\nDiagnosing Trigeminal Neuralgia\nNo one test can be used to diagnose trigeminal neuralgia. Your doctor may request an MRI to determine the cause of your pain, as well as perform a clinical evaluation and review of your patient history.\nTreatment Options for Trigeminal Neuralgia\nA number of treatment options are available for trigeminal neuraligia. Your doctor will consider your specific symptoms and triggers, as well as your age and gender when determining the best approach for treatment.\nPatients are often given medication, such as anti-convulsants, to control symptoms. Anti-convulsants can help reduce pain and relieve some nerve impulses. If medication isn\u2019t effective, your doctor might consider surgery,\u00a0including microvascular decompression.\nUPMC is one of the nation\u2019s leading centers for microvascular decompression, a minimally invasive surgical procedure that treats the cause of trigeminal neuralgia, offers the most long-lasting relief, and minimizes risk of postoperative side effects.
