I have a 16yo paint gelding with no history of lameness or injury. Starting in November he seemed stiff on the left side. He started repeatedly switching only his back feet to the wrong lead when cantering clockwise on the lunge line. He also wouldn’t extend his trot when working clockwise on the rail, breaking into a slow lope to take the corner instead of trotting. Everything in the other direction remained fine. He has a slight roach back and is very stiff when left in his stall for a day but otherwise muscles look great. No signs foot problems. He struggles up the barn ramp or small hills, taking smaller strides with his left-front/right-hind legs. He bobs his head more to the right when walking.
The vet X-rayed and diagnosed him with hock arthritis four days ago and injected both hocks but my boy doesn’t seem one bit better today. Based on everything I’ve read, my gut instinct is it’s the SI joint even though he didn’t seem overly bothered during flexions and when pushed in that area of his body. The repeated changing of legs behind on the right lead screams SI pain to me. But then the vet suggested starting with EPM testing instead.
What would you do? Anyone been faced with possible EPM versus SI joint pain before? Should I just start with the chiropractor first (he’s never been adjusted)??
I’ve finally learned what “worried sick” literally feels like. I just want my horse to be comfortable
