A couple of days ago, I tried loping her in a roundpen and she didn't seem to want to. I didn't push her, but eventually she tried and ended up just slipping and looked uncomfortable.
Yesterday, I decided to just spend some bonding time with her. I was scratching her to see if there was a spot she liked and rubbing her all over trying to see if there was a spot causing her pain. Turns out there was. I got to her left hip and she curled her neck down like she was going to buck. And all I did was apply a small amount of pressure. I did it again to make sure and she did buck.
The BO told me I should call a chiropractor, but the closest one is over an hour away and would probably cost quite a bit just to have them drive up.
Any other suggestions?
