Most back pain is caused by muscle strain, trauma, or deformity. About 10 percent of back pain is caused by a systemic illness.
Back pain can develop anywhere from the top of the neck to the bottom of the spine.
The pain can be in one small area or spread across a wide area. It may also spread out from a central point. Cause Back pain has many causes, including degeneration of vertebrae, infection, tumor, overuse, and trauma. The exact cause of pain may be difficult to identify, since it can emanate from soft tissue, bone, disc, or nerves. Risk factors for low back pain include jobs that require repetitive lifting, exposure to vibration produced by vehicles or industrial machinery, and cigarette smoking.
