In Health and Safety we cover a MAZE of topics and subject but I must admit being in the 50 club this one makes you pay attention twice because of when it can show up!
Trigeminal neuralgia (TN, or TGN), also known as prosopalgia, suicide disease, or Fothergill’s disease is a neuropathic disorder characterized by episodes of intense pain in the face, originating from the trigeminal nerve. The clinical association between TN and hemifacial spasm is the so called tic douloureux.
TN is a disorder of the fifth cranial (trigeminal) nerve. The typical or “classic” form of the disorder (called TN1) causes extreme, sporadic, sudden burning or shock-like facial 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.
The human face has two trigeminal nerves, one on each side. Each nerve splits into three branches which transmit sensations of pain and touch from the face, mouth, and teeth to the brain. Most cases of trigeminal neuralgia are believed to be caused by blood vessels pressing on the root of the trigeminal nerve.
