You have a lumbar spinal foraminal narrowing or stenosis. Foramen is a bony tunnel and spinal nerve lies within foramen. The narrowing is caused by protrusion of disc at L5 and S1 level of lumbar spine. The foramina narrowing at L5 to S1 causes pinching of L5 lumbar spinal nerve resulting in radicular pain. The L5 radicular pain travels on outer side of leg below knee and front of the foot. Rarely pain is felt above knee on lateral or outer side. You should get Myelogram done to evaluate the lumbar nerve and asses the damage.
