Hi, I had my horse to the vet because when he runs he has a head nod. The vet agreed that the horse is sore and tried nerve blocking to locate the lameness tried the foot and not much improvement, tried the ankle slight improvement then she blocked a nerve just above the ankle and said he can't feel anything from that point to bottom of hoof and he came sound. After that she took alot of xrays of the foot and ankle and couldn't see anything. She tried hoof testers and never flinched. At that point she said to give the horse stall rest and bring him back slowly. Anyone have any ideas of things she may have missed? Things I could try?
