Symptoms of Spinal Cysts. Patients with a spinal cyst may not experience any symptoms if the cyst remains small and stable. As the cyst progresses and becomes more severe, it may cause pain in the back that travels down the legs as well, and can also lead to spinal stenosis, which may cause pain, cramping and numbness.
However, if the synovial cyst expands or if more cysts form, spinal stenosis may begin to develop. Spinal stenosis is the narrowing of the spinal canal, which in this case would be caused by the formation of synovial cysts along the spine. The cysts may compress a nerve root in the spinal canal and result in chronic lower back pain.
