A 2007 British Medical Journal article entitled 'Trigeminal neuralgia and its management' describes the discomfort associated with this condition as "the worlds worst pain".
Anyone who has experienced this condition will know how intense this pain can be. It has a shooting nature and can be felt throughout the head and in particular in the jaw, teeth and gums. Often the pain is too intense to eat or drink. The nerves become extremely sensitised, with even a gentle breeze on the face being enough to cause unbearable pain.
