Cervical Disc Degeneration
Discs are made of woven cartilage strands surrounding an inner gel-like center. As the body ages, the water content in the disc can diminish by 20% or more, with the cushioning effect reducing, causing increased contact and wear. When the cervical discs degenerate, they are less able to absorb the vibration or shock between your vertebrae caused by normal motion.
Eventually, the disc wears to the point that it loses the height it needs to keep the vertebrae separated as they should be, leading to undue pressure on the nerves that run down the outside of the vertebrae. This will often cause pain or numbness in the arms and neck and interfere with mobility.
