"Low-back" problem?: You may be feeling the result of what doctors call a "lumbar radiculopathy." this describes a pinching or pressure on the nerve of your low-back as it branches off your spinal cord and starts to travel down your leg all the way to your toes. This is caused because the bones of your back and the discs that sit between the bones are not healthy. You may have arthritis in your back or other problem.
