1. Herniated Disk

If you have experienced an injury or accident that has affected your spine then you may also have weakness in legs. A herniated disk in the lower or upper back is one of these causes.

Your spine is made up of twenty-six bones called vertebrae. In between these bones are soft disks filed with a jelly-like substance. These disks act as a cushion so that the vertebrae do not grind against each other.
