We are he is going to a premier dianostician center on thurseday, however in defense of my vet she did not see him until the end of last week as she was on vacation. My farrier is the one who thought it was an abcess because my horse was sensitive on his heel on the exact same place where his last 2 abcesses have blown out. My chiropractor thought the problem was in his back after having to adjust his LS joint in all three directions which he has never had to do before on my horse, and my horse objected heartily to the chiropractor touching him there. The farrier after hearing this agreed and told me that my horse had been hard to shoe not wanting to pick up his hind legs, or keep them up, which is also unusual for my horse. So anyways no matter what it turns out to be he is going out to pasture for at least a month, and will still be getting the injections because they are anti inflammatory and have no side effects and he has been working quite hard and needs a break, physically and mentally.
