 I am Dr. Saurabh Verma and I am the Head of Department at the Department of Spine Care, Manipal Hospital, Dwarka. Today, we shall be discussing about sciatica. Sciatica is defined as any pain which is going down the leg in the distribution of sciatic nerve. The sciatica nerve arises from the lower number plexus, goes around in the buttock area and goes down the leg on both sides. Typically, the sciatica pain usually occurs on one side of the body, however, it may occur baratorily. Sciatica pain is usually due to irritation of the sciatica nerve. The most common cause is the prolapse vertebrate disc in the lower number spine, however, it may be due to muscle sprain, an entrapment of the sciatica nerve within the piriformis fossa by the piriformis muscle. Usually the sciatica pain which is mild usually settles down over the period of time with rest and over the counter medications, however, one should seek medical attention if the sciatica pain is severe, associated with tingling and numbness in the legs, altering with the bladder and bowel symptoms and causing weakness in the legs. Sciatica pain usually does not require any surgery and is still subsiding over the period of some rest and over the counter medications, however, if it is associated with severe pain or causing bladder to bowel discomfort or is associated with motor weakness, may require surgery.
