In addition, the exact cause of pain may be difficult to identify since it can originate in soft tissue, bone, discs or nerves. People who smoke, work at jobs that require repetitive or heavy lifting or involve vibration from vehicles or industrial machinery are more likely to develop low back pain. Certain sports, such as cross-country skiing, or driving a vehicle for a long time can also cause back pain.
Diseases such as spinal osteoarthritis, spondylitis and compression fractures can also cause pain. Some of these diseases are more prevalent in the elderly; consequently older people are at higher risk for back pain.
