where is your sciatic nerve located in your back
The sciatic nerve is one of the longest nerves in the human body. At its thickest point, it can measure the width of a thumb. This nerve starts at the back's lumbar region and continues all the way down the back of the legs, ending at the toes. The sciatic nerve is made up of two different branches, one branch for each side of the spine. The nerve has root endings at several places in the spine, which include two endings in the bottom two vertebrae in the lumbar spine.
