A herniated disc occurs when the intervertebral disc's outer fibers (the annulus) are damaged and the soft inner material of the nucleus pulposus ruptures out of its normal space.
Q. After I retired last year, my wife and I began walking for exercise to help the back problem I have had for years. I have noticed over the past few months that I get a burning pain in my legs after walking about 10 minutes. It goes away if I rest but then comes back again. Is this something I should be worried about?
