At least 80 percent of Americans will experience low back pain in their lifetime. Most low back pain is the result of an injury, such as muscle sprains or strains due to sudden movements or poor body mechanics while lifting heavy objects.
Low back pain can also be the result of certain diseases, such as:
* Cancer of the spinal cord
* a ruptured or herniated disc
* sciatica
* arthritis
* kidney infection
* infections of the spine
