Low back pain is common. Almost everyone has back pain at some time in their life.
Often, the exact cause of the pain cannot be found. A single event may not have caused your pain. You may have been doing many activities, such as lifting the wrong way, for a long time. Then suddenly, one simple movement, such as reaching for something or bending from your waist, leads to pain. Low back pain that is long-term is called chronic low back pain.
Low back pain may be due to a herniated disk, in which part of the spinal disk pushed onto nearby nerves. Normally, the disks provide space and cushion in your spine. If these disks dry out and become thinner and more brittle, you can lose movement in the spine over time. Many people with chronic back pain have arthritis. Or they may have extra wear and tear of the spine, which may be due to; heavy use from work, sports,Injuries, fractures or surgery
