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.
When a disc in the spine is traumatized by any injury to the neck or back, the disc becomes weakened and can bulge or protrude into the spinal canal. The bulge can occur in the neck (known as a cervical bulging disc), mid-back (thoracic bulging disc) or lower back (lumbar bulging disc). When a disc has a significant protrusion, it can compress a nearby nerve root, which can cause pain at the location of the bulging disc injury along the spine.
