There isn't usually an underlying condition causing back pain - nothing shows up in tests and nothing is permanently damaged. This is called simple or non-specific back pain. Nine out of 10 people with simple back pain recover completely within six weeks.
You're more likely to develop simple back pain if you:
stand, sit or bend down for long periods
lift, carry, push or pull loads that are too heavy, or if you go about these tasks in the wrong way
have a trip or a fall
are stressed or anxious
being overweight
Muscle strains are the most common cause of low back pain. Patients may or may not remember the initial event that triggered their muscle spasm, but the good news is that most episodes of back pain from muscle strains resolve completely within a few weeks.
A ruptured intervertebral disc, also called a herniated disc, is another common cause of back pain. How to treat the back pain from a herniated disc depends on the particular individual and situation.
Discogenic back pain is thought to be a common cause of low back pain. Discogenic back pain cis the result of damage to the intervertabral disc, but without disc herniation. Diagnosis of discogenic back pain may require the use of a discogram.
Spinal stenosis causes back pain in the aging population. As we age, the spinal canal can become constricted, due in part to arthritis and other conditions. If the spinal canal becomes too tight, back pain can be the result.
Arthritis most commonly affects joints such as the knees and fingers. However, arthritis can affect any joint in the body, including the small joints of the spine. Arthritis of the spine can cause back pain with movement.
Spondylolisthesis causes back pain because adjacent vertebra become unstable and begin to "slip." The most common cause of spondylolisthesis is due to degenerative changes causing loss of the normal stabilizing structures of the spinal column. If the spine becomes unstable enough, back pain can become a problem.
Osteoporosis can cause a number of orthopedic problems and generalized discomfort. Back pain from osteoporosis is most commonly related to compression fractures of the vertebra. Osteoporosis causes weak bones and can lead to these fractures.
