@johannab Sometimes surgeons miss where the spine issue is. If there is spinal cord compression in the neck, it can cause problems with the lower body and walking. I had these symptoms. Doctors need to look at the entire spine for compression of the spinal cord. Aside from that, there may be possible compression at the nerve roots which are more specific connections and better understood. If it's the spinal cord getting compressed, it is hard to pinpoint exactly what nerve fiber in that big bundle is getting squeezed. You may have to speak up and ask about this if your entire spine has not been imaged.
