A vet is definitely called for. The original symptoms sound like a back or leg injury to me. Leg injuries could include things like luxating patella, Legg-Calve-Perthes disease, or ACL injury, and these things need to be ruled out. I don't know about the others, but luxating patella symptoms can come and go. Hopefully it will turn out to be something minor or treatable.
