I was fox hunting with my boy a couple of months ago. He hit a jump hard with his hind leg and busted the carbon fiber on the front of his Delmar boot (glad he was wearing his boots). He ended up with a brushed periosteum and was never lame or sore, but the bump left there was warm for about a month. The bump is slight, right on the middle front about 3 inches long, one inch wide and raised a few millimeters. Have any of you fox hunters or eventers ever had a similar injury to your horse? And if so, did the bump ever go away, and how long did it take?
