Disc herniation. With normal aging, the intervertebral discs slowly degenerate with loss of fluid or hydration. These natural changes combined with weakening of the outer covering of the discs provides the mechanism for development of a disc herniation. The strength of the discs and alignment of the spine are genetically determined and also plays a parts in the process.
Herniated disc. Yes. High impact exercises will often make the pain worse. Gravity and jarring forces often cause the herniated disc to compress the nerve. Stationary bicycles, elliptical machines, and pool exercises are generally good options. Try an inversion table or traction to relieve the pain. Any exercise that makes the pain worse should be avoided.
