Causes of fluid at facet joint l3-4 and l 4-5 level in male aged 31 years old with mild degenerative changes with small schmorls nodes at l 1,l 2,l 3?

Back pain: Fluid in the facet joints is caused by inflammation of the joint. The degenerative changes of the spine and schmorl's nodes are typical of arthritis in the low back. Lumbar levels L3/4 and L4/5 are the most common location for arthritis to begin. Most cases of spinal stenosis originate in this area. Do daily back exercises and avoid tobacco products to reduce pain and improve back function.
