Sciatica

Sciatica is nerve pain from an injury or irritation to the sciatic nerve, which originates in your buttock/gluteal area. The sciatic nerve is the longest and thickest nerve in the body. It’s actually made up of five nerve roots: two from the lower back region called the lumbar spine and three from the final section of the spine called the sacrum. The five nerve roots come together to form a right and left sciatic nerve.

On each side of your body, one sciatic nerve runs through your hips, buttocks, and down a leg, ending just below the knee. The sciatic nerve then branches into other nerves, which continue down your leg and into your foot and toes.
