.......Personally I'd go to a vet chiropractor and see what they have to
say.

I was thinking of this. He seems perfectly alright today and he is
off his meds.

When he was accute, flexing his spine produced a pain-filled yelp.

I wonder if putting his spine in extension would help. I can
easily conditioned him to do this. He extends his back whenever
he gets up from a nap.
