Trigeminal neuralgia is a sudden, severe facial pain, described as sharp, shooting or like an electric shock.It usually occurs in sudden short attacks lasting from a few seconds to about two minutes, which stop just as abruptly. In the vast majority of cases it affects part or all of one side of the face, with the pain most commonly felt in the lower part of the face. Very occasionally it affects both sides of the face, but not normally at the same time. 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. Treatment can be subdivided into pharmacologic therapy, percutaneous procedures, surgery, and radiation therapy. Adequate pharmacologic trials should always precede the contemplation of a more invasive approach. Canada people around 629,313 among the total population are suffering from this disease that is 3.68% of the population effected.
