When that becomes comfortable, saddle and lunge. It may just be one of those things where completely starting over is the best option. I am very lucky that I have many friends and a couple of great trainers to lean on. Good luck!
I had to read back to the beginning because I was confused as to whether this was my thread or one I'd commented on (Darla's) lol.
As I said before, I don't always ride her or even work her when I saddle her. The saddles I use fit her and her back is not sore. It was a problem from day one with me and she'd had a year off from riding before that, so just those facts alone rule out the saddle fit making her that way. The only other time she's been ridden was when she was being trained for riding last spring.
Another thing too - when I take the saddle off of her she immediately shies away from it. The only time she accepts it is when it's on her back. I'll need to get a video or something to clarify what she's doing. It's really strange!
