This is a case of a 24 year old female with difficulty walking and shooting pain down both legs.
The first MRI image shows degenerated (damaged) disks at the the three lowest disks L3/4, L4/5, and L5/S1. Compare to the normal L2/3 disk above. The L4/5 level shows a massive central disk herniation with severe stenosis (narrowing) of the spinal canal. This can be seen on the axial image where the nerves are severely pinched. This causes shooting pain down the leg.
We performed a discectomy surgery and removed a large piece of disk pinching the nerves. Luckily all of her leg pain is gone and her foot drop has resolved. Many times if left for too long, chronic nerve damage and foot drop will never get better.
Unfortunately in the long term that severely damaged disk will continue to worsen and cause low back pain. The best way to decrease the rate of deterioration is keeping your weight low, keep the core strong, and avoid smoking.
