TN (Trigeminal Neuralgia) is a pain that is described as among the most acute known to mankind. TN produces excruciating, lightning strikes of facial pain, typically near the nose, lips, eyes or ears.
It is a disorder of the trigeminal nerve, which is the fifth and largest cranial nerve.
TN (Trigeminal Neuralgia / tic douloureux) is a disorder of the fifth cranial (trigeminal) nerve that causes episodes of intense, stabbing, electric shock-like pain in the areas of the face where the branches of the nerve are distributed - lips, eyes, nose, scalp, forehead, upper jaw, and lower jaw. By many, it's called the "suicide disease". A less common form of the disorder called "Atypical Trigeminal Neuralgia" may cause less intense, constant, dull burning or aching pain, sometimes with occasional electric shock-like stabs. Both forms of the disorder most often affect one side of the face, but some patients experience pain at different times on both sides. Onset of symptoms occurs most often after age 50, but cases are known in children and even infants. Something as simple and routine as brushing the teeth, putting on makeup or even a slight breeze can trigger an attack, resulting in sheer agony for the individual. Trigeminal neuralgia (TN) is not fatal, but it is universally considered to be the most painful affliction known to medical practice. Initial treatment of TN is usually by means of anti-convulsant drugs, such as Tegretol or Neurontin. Some anti-depressant drugs also have significant pain relieving effects. Should medication be ineffective or if it produces undesirable side effects, neurosurgical procedures are available to relieve pressure on the nerve or to reduce nerve sensitivity. Some patients report having reduced or relieved pain by means of alternative medical therapies such as acupuncture, chiropractic adjustment, self-hypnosis or meditation.
