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.
It's possible. However, Tarlov cysts are an uncommon cause of back pain. Tarlov cysts are fluid-filled sacs that most often affect nerve roots at the lower end of the spine. Such cysts typically cause no symptoms and are found incidentally on magnetic resonance imaging (MRI) studies done for other reasons.
