The C5-6 disk does not yet seem to be affecting the spinal cord. It has squeezed the canal down to a width of 7.5mm, is narrow. Your spinal canal should be maybe twice that wide. The spinal cord itself shouldn't be less than 8mm-15mm. The C5-6 disk does not yet seem to be affecting the spinal cord. It has squeezed the canal down to a width of 7.5 though, which is narrow. Your spinal canal should be maybe twice that wide. The spinal cord itself shouldn't be less than 8mm. This could be causing problems with any of the nerves from this level down, which may include some of your arm nerve and some nerve below shoulder.
