A couple weeks ago I was riding an 8 year old OTTB that I lease (and looking to purchase soon) when he stumbled a little on his back legs. Immediately after he started limping a bit, coming from his hind. My trainer says it wasn't visually that obvious, but it felt pretty obvious.
My trainer immediately wraps his legs, but no swelling ever occurs. She ends up thinking it may be a pulled muscle so she brings out a chiropractor to work on him. The chiropractor rules out any joint issues. After a week off of riding and few weeks of just trotting the straightaways of the arena he seems to be back to normal. After about 3 weeks of that, we finally started cantering and jumping crossrails and he seems perfectly fine.
I'm not sure if they every figured out exactly what happened, but I'm concerned because I would like to know if its something that may reoccur in the future, or cause permanent damage. It's never happened in the past. So I'm wondering if it really was a muscle issue or what.
This probably isn't relevant, but his front hooves are slightly uneven. One narrower then the other. I've done some research on this, but can't seem to come up with a definite answer if this is something that can cause him to become permanently lame. I've asked one of my trainers about this and he claims that its hereditary for thoroughbreds sometimes (I don't think I bought that for some reason). Then I have another trainer telling me that the uneven-ness can cause him to be uneven all over, thus sore. Ahh I'm so confused!
I do have a vet coming out this week for a pre-purchase exam, but I just want to get other opinions. He's a big purchase so I just need some advice!
