Lumbago is the general term referring to low back pain, and the two terms are often used interchangeably. The underlying causes of low back pain can be complex and are not always readily apparent. When determining the underlying cause of lower back pain , two main factors help guide the physician in making a preliminary diagnosis:
Low back pain with referred pain can vary widely with regards to severity and quality. It tends to be achy, dull and migratory (moves around). It tends to come and go and often varies in intensity. It can result from the identical injury or problem that causes simple axial back pain and is often no more serious.
Lumbar spinal stenosis ( LSS ) is a medical condition in which the spinal canal narrows and compresses the spinal cord and nerves at the level of the lumbar vertebra . This is usually due to the common occurrence of spinal degeneration that occurs with aging. It can also sometimes be caused by spinal disc herniation, osteoporosis or a tumor. In the cervical (neck) and lumbar (low back) region it can be a congenital condition to varying degrees. Spinal stenosis may affect the cervical or thoracic region in which case it is known as cervical spinal stenosis or thoracic spinal stenosis. In some cases, it may be present in all three places in the same patient.
