Pain that travels from the lower back into the leg is often called sciatica. It can make sitting, walking and sleeping difficult. At Dr. Bhanji Physiotherapy & Fitness Center in Versova, sciatica treatment begins with a detailed assessment to find the real cause, followed by a personalised physiotherapy plan to ease nerve irritation and help you move with comfort. The sciatic nerve is the longest nerve in the body. It starts from nerve roots in the lower back, passes through the buttock and runs down the back of the thigh into the leg and foot. When this nerve or its roots become irritated or compressed, pain can spread along its path. This is what people usually mean by sciatica. It is a description of symptoms, not a diagnosis in itself, which is why understanding the cause matters.
