I looked at previous posts and see that at one point Scooter was diagnosed with CT and was on Temeril P for a few days and it was working! Is he still on it? I had advised you speak with your vet about a flouroscopy...did you do that?

I am very confused about what diagnostics have been done on Scooter...that may be the real issue here. I strongly encourage you to have him seen by a specialist so you can get to the bottom of this issue and help Scooter feel better and you as well.
