Problems up in the cervical (neck) region can definitely cause problems lower down. All the nerves run through the spinal cord up there and on to other locations. There are nerve connections from the spinal cord down into the limbs and other extremities, but all the upper motor neurons run from the brain on down the spinal cord and pass through the cervical region where the syrinxes most often are. So obviously problems up here - pressure, kinks, etc. -- can cause problems in the lower part of the body as well as the front half.
That is weird that Maxx's syrinxes are down at the base of his spine -- down by his tail?? I've never heard of that.
The study I"m taking Rory to is just looking at the skull area. She kept saying they are looking for the chiari?? I assume she meant chiari malformation... If he has it i'm sure i'll have to redo the MRI which is annoying...
