What are symptoms. What the risks are of not treating those anatomical findings depends and what your symptoms are. The spinal stenosis is of more concern as it may lead to a more severe neurological deficient and the potential for permanent damage a concern. If there are no symptoms, the risks may be less. In any event, best talk to you Doctor.
