Lumbar facet syndrome
There are two facet joints that lie behind the discs, and together with the discs, control all movement of each spinal segment. The facet joints are put under more stress when we bend backwards. The main mechanism of injury of a facet joint is severe sudden, compressive, or repetitive movements such as over stretching. Other contributing factors include repetitive wear and tear, poor posture, sedentary lifestyle, or weak back muscles. The symptoms of back pain and spasm can be felt on one or both sides. If your pain is reproduced with bending backward then you may have an element of facet joint irritation. Disc and facet degeneration often occur together. Other aggravating factors include prolonged standing, sudden movement such as sit to stand, rotating the trunk, or bending to the side. Pain typically decreases with walking, lying with knees bent toward the chest and bending away from the painful side.
