Trigeminal neuralgia is inflammation of the trigeminal nerve, causing intense facial pain. It is also known as tic douloureax because the intense pain can cause patients to contort their face into a grimace and cause the head to move away from the pain. The obvious movement is known as a tic. Patients may find immediate and satisfying relief with one medication, typically carbamazepine. However, because this disorder may remit spontaneously after 6-12 months, patients may elect to discontinue their medication in the first year following the diagnosis. Most must restart medication in the future. Furthermore, over the years, they may require a second or third drug to control breakthrough episodes and finally may need surgical intervention. It has been suggested that lack of neurogenic inflammation in TGN is evidence against a major peripheral nervous system involvement. However, vasodilatation is known to occur in TGN and it normalizes when pain is controlled. United States people around 1,07,51,538 among the total population are suffering from this disease that is 3.56% of the population effected.
