Current studies suggest that 80% of the population will suffer from lower back pain during their lives; low back pain is the leading cause of disability in the work place and it is the second most common reason people visit the doctor after the common cold. Most cases of lower back pain can be linked to a general cause—such as a muscle strain or injury, or overuse. These can be treated conservativley with non surgical means such as anti inflammaroty medication and physical therapy. However, sometomes, back pain can come from a specific abnormal condition of the spine, most commonly: Herniated Disc, Degenerative Disc Disease, Spondylolisthesis, Spinal Stenosis, and Osteoarthritis. There are a number of less common conditions that cause low back pain as well, such as sacroiliac joint dysfunction, spinal tumors, fibromyalgia, and Piriformis Syndrome.
