Over time, it is natural for the discs in the spine to show signs of wear and tear. They will begin to break down and will not offer the same flexibility as they once did. However, if this causes pain then it is likely you are suffering from Degenerative Disc Disease. Spinal Discs have a tough outer wall and a soft inner core. As we age they can dry out and begin to crack resulting in herniated discs. Degenerative Disc Disease causes pain in the lower back, buttocks and upper thighs. The pain is usually worse when sitting, bending, lifting or twisting.
