I had discovered something, discovered something by accident. That ewe's life had been saved not by medicinal therapy but simply by stopping her pain and allowing nature to do its own job of healing. It was a lesson I have never forgotten; that animals confronted with severe continuous pain and the terror and shock that goes with it will often retreat even into death, and if you can remove that pain amazing things can happen. It is difficult to explain rationally but I know that it is so.
