Medical experts rank back pain as one of most common medical conditions, affecting an estimated 80% of all Americans at some point during their lives. What makes back pain particularly troublesome, is that it is a medical condition that affects people of all ages, genders, and ethnic backgrounds. But what exactly causes back pain?
An adult spine consists of a stack of 24 bones called vertebrae, plus the bones of the sacrum and coccyx. These bones support the human body and protect the spinal cord’s major column of nerve fibers connected to the brain. These fibers run through the vertebrae via the spinal canal. Between each vertebra are discs made of cartilage and filled with a gel-like material, these act similar to a shock absorber. Also, ligaments, muscles, tendons and small joints called facets help hold the vertebrae together.
