What can I do about a pain in my lower back?

Chronic lower back pain usually has a more insidious onset, occurring over a long period of time. Physical causes may include osteoarthritis, rheumatoid arthritis, degeneration of the discs between the vertebrae or a spinal disc herniation, or tumors (including cancer). However, some causes are psychological or emotional, and have been diagnosed as TMS or tension myositis syndrome.
