Anatomy of the Pain
On your lumbar spine or lower back, a disc lies between each of your vertebra. These discs, function like shock absorbers, as they mitigate pressure and maintain the flexibility of your spine by acting as a support framework for body as it moves.
At the same time, stress on your spine occurs while bending or twisting, whereby the cushioning effect of the discs work to absorb these forms of impact to mitigate the daily wear and tear inflicted on your vertebrate and bones.
Nature of the Condition
Forms of degenerative disc disease often spread from the spine to the lower extremities of the body including the upper thighs and buttocks, though it remains rooted in the erosion of back disc integrity.
