Sciatica is defined as pain that radiates from the lower back into the buttocks and down the back of one or both legs, caused by the irritation of the sciatic nerve, the largest nerve of the body. It usually begins as an acute pain in the lower back, then radiates down the back of either or both legs. There are pairs of nerves that exit the spine in the lower back. These nerves make up what we know as the sciatic nerve. If the disc is swollen, bulged or herniated, the result is pressure on those nearby nerves. This can cause tremendous pain, and normal daily activities become almost impossible. In my practice, I have successfully treated hundreds of patients with sciatica.
