No one has mentioned this - but have you considered asking for a prescription for gabapentin as that is the main drug used for CM/SM pain? I presume that the vetergesic injection is something that he is not receiving on a regular basis but was just given initially, and he is only taking the tramadol at this point? I definitely wouldn't want to give vetergesic on any kind of regular basis as this is a pretty powerful opioid. This is not a drug that is commonly used for CM/SM pain.

Tramadol alone isn't very effective either for CM/SM pain. It is generally used to augment gabapentin or pregabalin.
You said that the vet is introducing NSAIDS - has that started yet and which one is under consideration?
I'd really recommend that you consider adding gabapentin asap rather than waiting for a neurology consult given the amount of pain that you describe.
