Common types of lower back pain in young adults (< 60 years old)

1. Symptoms: Leg pain (sciatica) and possible numbness
   Pain that radiates through the buttocks, as well as pain and possibly numbness that radiates down to the foot, is frequently caused by a disc herniation in the lumbar (lower) spine. This type of pain is usually worse after a long period of standing or sitting.

2. Symptoms: Pain with certain movement and positions
   Low back pain in young adults that is caused by certain positions and movements (such as bending forward, running) is commonly caused by a syndrome called degenerative disc disease. The low back pain symptoms of degenerative disc disease can become chronic and may tend to fluctuate and at times become significantly worse.

Common types of lower back pain for older adults (>60 years old)

1. Common symptoms: Lower back pain that is worse in the morning and in the evening, and stiffness
   Lower back pain that is most pronounced first thing in the morning and later in the day is often caused by facet joint osteoarthritis (degenerative arthritis), a condition that involves breakdown of the cartilage between the facet joints in the back. The pain and stiffness is a result of the lack of cartilage between the joints.

2. Pain down the legs when walking and standing upright
   Leg pain (sciatica) that occurs when walking, and increases with more walking, can be caused by conditions such as lumbar spinal stenosis or degenerative spondylolisthesis. Both conditions place pressure on the nerves at the point where they exit the spine. Standing upright, such as in normal walking, increases pressure on the nerve and results in leg pain.
