The sciatic nerve is one of the largest nerves in the body. It begins at the lower spine and runs through the buttocks and down the lower limb to the foot. This nerve provides movement, feeling and strength in the legs.
About 40% of the world’s population will suffer from sciatica at some point in their lives. Sciatica is a condition that can cause pain, numbness, tingling, and weakness in the lower limbs, but it is often mistaken for lower back pain or even leg cramps. It starts as a pressure or pinch on the nerve, and then continues as a pain down the back to the legs.
