I have a mare in her teens who has always been a great horse. Never caused any issues, always willing to please. However a month ago I watched her tumble into a small tree/bush. She scratched her head but otherwise seemed fine. No issues with walking, soreness, etc. Lately she's become one sided. Not wanting to bend or lung clockwise. I have called the vet as well as a chiropractor. I have made arrangements for her to see a vet next week for xrays and if they check out the chiropractor is coming out to make sure she didn't knock something out of whack. However if neither of these things fix the issue where would you start? Note I will be starting with groundwork as I'm not in a position to ride for the next few weeks. Edited to add * When the incident happened my vet was contacted and it was decided to watch her carefully and ensure she was fine if not he would come out. She never seemed dazed by the accident and we figured it was like one of those normal things only a horse could do.
