I can try this, but in all other ways he is robust. He doesn't act like a sick roo otherwise, and there is no red striation on his leg indicating the injury went septic. I have amoyxicillian (sp?) Should I try that? I looked up dosage previously for the crop surgery....Have you tried an antibiotic? It could be a systemic infection of some kind. It's not likely but it could be. They grey on his face is making me think heart problem and the only connection to an injury that I can think of is blood infection.
However I am a microbiologist and my brain means towards bacteria when there is no other cause apparent......
