As we age, our body especially our bones also age. Physical work and stress also add up to the reasons why our body sometimes ache and deteriorate. As we age, we tend to feel uncomfortable pain on our spine and the lower back. This pain may also be caused by injuries and other numerous factors. Our spinal cord which is located at the back of our torso is protected by 33 vertebrae which are made of bones. Between each vertebra are soft discs with a ligamentous outer layer. These ligaments serve as a protection of the vertebra and the spinal column. We experience back pain because of the wear and tear which causes the weakening of the disc, thus aging. Another reason is what is scientifically termed as herniation or the swelling of the disc which causes pain or numbness.
