Sciatica is a term used to describe pain caused by sciatic nerve irritation. Patients experiencing sciatica most often complain about pain radiating down the back of their leg, reducing their mobility. There are certain risk factors that increase the chance of developing sciatica, including age, height, mental stress, and cigarette smoking. Ask Dr. Swain how he can gently and effectively help free you from pain and disability caused by your sciatica.
