I am posting this picture of a bruised periosteum that my horse sustained while fox hunting last November. He banged his rear canon off of a jump and luckily he was wearing Delmar boots. He hit so hard that the carbon fiber split! Anyway, he was never lame, it didn't seem to bother him when touched, and it only had slight heat for a few weeks. It's been 4 months now, and the bump is still there, my question is this; if anyone's horse has had a similar injury, did the bump eventually go away?
