TRIGEMINAL NEURALGIA

Trigeminal Neuralgia (TN) is defined by the International Association for the Study of Pain (IASP) as sudden, usually unilateral, severe, brief stabbing or lancinating, recurrent episodes of pain in the distribution of one or more branches of the trigeminal nerve (Merskey et al.). Less often patients may have a constant, aching or burning sensation. A tingling sensation or aching may also precede the pain episodes.
