Ok, I'm thinking his last toe is broken. I finally worked up the nerve to investigate a bit more thotoghly. He screamed in pain any time I got near the last toe. I couldn't get even removtely enough pressure on the toe to extend the nail and look to see what the nail looks like.

I gave him a pain pill, and will check in a bit once the meds kick in to see what he did to the nail. What one Earth has he done to himself now?
