We took a yearling colt to our vet Sat. with what we thought was a locking stifle problem. Vet checked him throughly also holding his leg while he walked and agreed that was the problem. He also did x rays to make sure no other problem. X rays looked fine. He said best treatment at this time was injection of iodine and almond oil into the joint , which he did. And to keep up in stall for 4 to 6 weeks. If not better by then suggests another injection. Actually seemed better Sunday, but today(Mon) he is noticeably worse. He is actually dragging his leg alot. We have also been giving 1cc of brute twice a day. Has anyone ever heard of this treatment for this, and if so does it sometimes seem to get worse before it gets better? Thanks
