Thanks for the information. It is possible that it could just be a soft tissue injury, although a joint injury cannot be ruled out without a proper veterinary exam and/or x-rays. Usually if there are no painful or swollen areas associated with any of the joints, a muscular or tendon injury is most likely. That may explain why it was better, then got bad again. It is very easy to re-aggravate a soft tissue injury. Sometimes a spinal cord problem can mimic that as well, though. I would also check under the paw
to make sure that there are no foreign bodies stuck there. If she is acting normal otherwise, you can always try confining her today and see how she is doing tomorrow, but if she continues to not bear weight on the limb, I would have your vet check her out and at the very least prescribe some safe pain medications. As far as human OTC pain medications, enteric coated aspirin is the only one that is somewhat safe, but it can still cause mild degrees of stomach bleeding
, so I do not usually recommend it. Plus, it can interfere with other medications she may be on or other medications your vet may want to prescribe. Please let me know if you have any other questions or concerns.
