Throughout the history of Neuralgia it has been discovered three times. The first recorded document was in the second century A.D by Aretaeus of Cappadocia, a contemporary of Galen who called the virus Tic Douloureux . The second recorded finding was by an Arab physician in the eleventh century. The full account of the virus was confirmed in 1773 by John Fothergill who presented a paper on Tic Douloureux to the Medical Society of London giving it the common name of Trigeminal Neuralgia.
TN is mainly transmitted through the Shingles or Herpes viruses. Trigeminal Neuralgia is when the Trigeminal nerve becomes irritated and swells until it rubs against other nerves and causes pain. After a member of a family has TN it can be passed on through generations.
