In the days before an episode begins, some patients may experience a tingling or numbing sensation or a somewhat constant and aching pain. The attacks often worsen over time, with fewer and shorter pain-free periods before they recur. The intense flashes of pain can be triggered by vibration or contact with the cheek (such as when shaving, washing the face, or applying makeup), brushing teeth, eating, drinking, talking, or being exposed to the wind.
TN occurs most often in people over age 50, but it can occur at any age, and is more common in women than in men. There is some evidence that the disorder runs in families, perhaps because of an inherited pattern of blood vessel formation. Although sometimes debilitating, the disorder is not life-threatening.
The presumed cause of TN is a blood vessel pressing on the trigeminal nerve in the head as it exits the brainstem. TN may be part of the normal aging process but in some cases, it is associated with another disorder, such as multiple sclerosis or other disorders characterized by damage to the myelin sheath that covers certain nerves.
Because there are a large number of conditions that can cause facial pain, TN can be difficult to diagnose. But finding the cause of the pain is important as the treatments for different types of pain may differ. Treatment options include medicines such as anticonvulsants and tricyclic antidepressants, surgery, and complementary approaches. Typical analgesics and opioids are not usually helpful in treatment of the sharp, recurring pain caused by TN. If medication fails to relieve pain or produces intolerable side effects such as excess fatigue, surgical treatment may be recommended.
Several neurosurgical procedures are available. Some are done on an outpatient basis, while others are more complex and require hospitalization. Some patients choose to manage TN using complementary techniques, usually in combination with drug treatment. These techniques include acupuncture, biofeedback, vitamin therapy, nutritional therapy, and electrical stimulation of the nerves.
The disorder is characterized by recurrences and remissions, and successive recurrences may incapacitate the patient. Due to the intensity of the pain, even the fear of an impending attack
may prevent activity. Trigeminal neuralgia is not fatal and is a unique diagnoses from hidden TMJ problems
