My horse has never had a problem with being back sore before, but of course a couple days before we're leaving for a big show, she's back sore. I don't think it's a problem with my saddle fitting, but i'm going to have a professional saddle fitter look at it just in case. I didn't do anything different the day before when I rode her! But when I got her out to ride her the next day she was cringing when I brushed her back! Any ideas on why she's sore all of the sudden? And what's a quick way to get her over it?!
