Where does the sciatic nerve originate and end?
It comes off the lower spinal cord (lumbar-sacral nerve roots) and dives behind an opening (obturator canal) in the pelvic bone before it branches off to supply the upper and lower legs and the feet. The pain from sciatica comes from pressure and swelling that results in the nerve pressing against the bones of the pelvis or spinal column.
