Trigeminal neuralgia is a type of intense recurring pain in the facial areas distributed by the trigeminal nerve. When an attack occurs, the pain is unbearable for the patient. Clinically, besides immediately taking medication or opting for surgical treatments after stabilization, applying a cold compress can also alleviate symptoms. Placing a cold towel on the painful facial areas can relieve spasms and pain, improve local swelling, raise the pain threshold, and subsequently reduce the sensation of pain.
