He's getting VERY bored already being cooped up and has taken to running around his stable. So I've decided to fence off a small area of flat paddock and let him go in there during the say so that at least he's outside and able to graze near the other horses. He seems to be much happier with this arrangement.
Today was his last day of being double buted, he's still a little sore but walking much better on it. So hopefully now that he'll be going back to one bute/day for another week, the swelling will go for good and I won't need to take him back for a re-scan.
