I can't help but think of my recent post (not sure how to link to it, but, click on me, and see my recent posts, perhaps?). Anyway, in short, my mare suddenly gave me a BAD, BAD, day. I had seen nothing like it, and, if someone else had ridden her, I would completely have assumed they 'caused' the problem. It would have been the most logical explanation. But, I had noone to blame (thank goodness), and, after MUCH to do, I have dismissed it as a mare day. She was 'winking' the next day, and, she (almost) completely reverted back to normal during my next ride. So, after reading your post, my first instinct, is, SHE IS A MARE. Hopefully your next ride is back to normal (or close to).
But, it is wise to do due diligence, and check everything thoroughly (saddle fit...did she get sore during her last ride, and now is telling you about it?), did YOU lunge her and take a look to see if she looked sound, from the ground? How were her ground manners, etc?
Writing those things, but thinking...mare.
