My 16 yr old tux has hurt her back hip and/or back. It was a week ago. We’ve been to the vets twice and are waiting to book her in for an X-ray. She was given buponorphine but she has a strange reaction to it. She stops sleeping and paces the room. But it did seem to ease her pain. Gabapentin does the same and metacam isn’t touching the pain. The vet said that’s the three choices! What can we do?
