I know your focus is on the back...but my concern, like yours is the failure to lay down. Back pain, whether neck or lower back, causes a dog to be reluctant to jump up or down...but not usually lay down.
Maybe you should call your vet in the morning and ask if the xray of the spine allows him to see the abdomen...and if not, go in for an xray of the abdomen. Why? I don't want to upset the vet...but to see if there is evidence of a tumor that this vet can't feel...like on the spleen or liver, something that would cause this dog to not lay down...the spasm may be a reaction to the pain.
Please keep me posted...
