Trigeminal neuralgia, also known as tic douloureux, sometimes is described as the most excruciating pain known to humanity. The pain typically involves the lower face and jaw, although sometimes it affects the area around the nose and above the eye. This intense, stabbing, electric shock-like pain is caused by irritation of the trigeminal nerve, which sends branches to the forehead, cheek and lower jaw. It usually is limited to one side of the face. As suggested by Rappaport and Devor,the above crossâexcitation may be at the root of the unique pain seen in TGN and offers a logical explanation for the extraordinary initial responsiveness of pain in TGN to almost any procedure aimed at the nerve. We think it is unlikely that the generator of pain is located in the central nervous system but central sensitization may well develop following prolonged barrage of nerve impulses which can explain the development of some features of atypical TGN. 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. Norway people around 2,51,538 among the total population are suffering from this disease that is 2.15% of the population effected.
