See below: It sounds like lumbar disc degeneration (and lumbar spondylosis). Spondylosis is a term referring to degenerative osteoarthritis of the joints between the centre of the spinal vertebrae and/or neural foraminae. If this condition occurs in the zygapophysial joints, it can be considered facet syndrome. If severe, it may cause pressure on nerve roots with subsequent sensory and/or motor disturbances, .

This is common in both disk herniations and spinal stenosis. Both can cause buttock pain, but in your age, a disk herniation is more likely.
