One of the most common problems seen in a primary care medical practice is low back pain. It accounts for more discomfort, lost work and productivity, and frustration for many patients than any other malady. Some think it is the price we, as humans, pay for walking upright. The lower back is a complex structure made of bone, muscles, connective tissue and nerves that, along with our legs, hold us erect, allow us to bend, run, twist, catch a football, or just lay down and rest. However, once a problem arises, the complexity of its structure makes pain in the lower back difficult to diagnose and treat. The lower back consists of a spinal column from the lumbar region of the mid-back down to the tail bone or coccyx. The spinal column consists of 5 lumbar vertebrae which are cylindrical bony structures with a ring like component behind the cylinder also made of bone. In between the vertebrae are disc shaped cushions filled with a gelatinous central core known as the nucleus pulposis

Pain may radiate to the buttocks or upper leg(s)
Signs and tests
A physical examination focused on the back, the abdomen, and the extremities may confirm back pain or muscle spasm , but the examination does not reveal a specific cause (such as a herniated disk) or any neurological problem (such as weakness or change in sensation).
X-rays of the spine are usually normal. Further work-up may include a CT scan or MRI of the spine .
