No, same on both reins. My gut feeling is that she's been back in work for two months now and probably just needs a few knots taking out of her pelvis. Just hoping it is muscular and not something lower down.
After my recent experinace my first call would be a good equine vet - if i had gone this route maybe i would have saved myself a potential permanantly lame horse, and maybe i would already be 5 weeks into box rest.
You should always go to your vet first. As a McTimoney-Corely practitioner myself we are not allowed to treat a horse without the vets permission. Even a phone call to discuss your horse maybe enough for the vet to refer you to a physio. Hope all's well.
