Your symptoms seem to be full body involvement and not specific to a nerve compression syndrome. Normally, with nerve compression, you would have one arm or one leg involvement. If you really had significant degeneration of both neck and lower back, you might have one arm and one leg involvement.
With bilateral arm and leg involvement, I would be more suspicious of a metabolic. Inflammatory or infectious process such as B12 defeciency, Lyme disease or even Lupis.
Neck stiffness is very common with degenerative disc disorders. If the cord is flattened, you can look in the myelopathy section of this website for symptoms related to that disorder.
