I would advise you to go ahead and get a vet's diagnosis. In my case, we are dealing with a ruptured acl and she is scheduled for surgery tomorrow morning. We knew there was a problem but we thought it was the hips, and x-rays confirmed. Had we focused on the knee also two months ago we could possibly be avoiding (expensive) surgery tomorrow. So, my point is in some cases strict crate/kennel rest can avoid surgery later if you catch it soon enough, but if you are only guessing at what may be the problem you may actually allow further damage as is what happened to us. My baby showed no real signs of pain either until it was too late to do anything but surgery to alleviate the problem. Good luck with your baby.
