It is an inflammation of the supporting tissues of the sciatic nerve in the leg. In Ayurveda, it is known as gridhrasi. The condition is caused by the aggravation of vaayu that has resulted from strain to the back due to poor conditioning, posture or due to back sprain caused due to structural damages such as ligament tear. Constipation and cold weather often precipitate an attack of this condition. Sciatica pain usually occurs on one side when your sciatic nerve is stretched or pinched, usually by a herniated disc, although narrowing of the spine or other vertebral abnormalities can also cause this pain. Sufferer may experience mild tingling sensation to severe pain, which could also cause immobility.
It isn't known why some people are prone to sciatica. Most often, pain begins with an injury, after lifting a heavy object or after making an abrupt movement. A number of conditions may make people susceptible to sciatica. A herniated disc, sometimes called a slipped disc, is the most common cause of severe sciatica.
Sciatica can also be caused by other problems, including inflammation, abscesses, blood clots, tumours and obesity. Arteriosclerosis can also cause chronic low back pain. When it blocks arteries in the legs, it may cause pain that resembles sciatica caused by spinal stenosis.
