Do you have a Gel Ice Wrap or anything? I would be inclined to apply something cooling tonight to try to reduce swelling tonight and maybe even start him on Bute with it being a previous injury site. Better to be a bit over the top now as playing catch up tomorrow. Will be keeping my fingers crossed that he hasn't aggravated it and is fine once the shoe is off. I really can't believe the run of bad luck you are having. So pleased that Keepers recent set back was something minor.
