Sciatica has always been misunderstood or misdiagnosed for lower back pain or leg pain because of similar symptoms. The word sciatica was first used in the 15th century and so its definition has evolved since then. There is a common misconception about sciatica that it is a form of diagnosis of the sciatic nerve root disorders but in reality sciatica is more of a set of symptoms. To clear all of these misconceptions, here is an all you need to know guide on sciatica.
What is sciatica?
The sciatic nerve is the largest nerve in the body with nerve roots in the lower part of the spinal cord and extends through the buttocks, back of your thigh to the lower extremities of your foot. Sometimes the five spinal nerve roots of the sciatic nerve in both the limbs are compressed or irritated due to various causes. This compression or irritation leads to a set of symptoms which includes lumbar pain, buttock pain, numbness or weakness in the leg, loss of control and tingling sensation in the leg. The pain caused by sciatica usually radiates from lower back to the back of the thigh and might go below the knee as well.
