Hello and welcome to YT! Unfortunately it's not under better circumstances.
I am not a vet but I have a dog with disc issues and it was the first thought in my head when I read your post. Can you tell me what the neurologist did to know there was no disc problems? It sounds like he didn't do an MRI, but did he do a myelogram or anything? It is very hard to find a disc issue in an x-ray.
