We had our follow up vet visit this evening, and still no answers. The x-rays came back worse but the internal exam by the vet had her confused. On the last internal exam Tiki completely freaked out and squealed and tonight he didn't even flinch. The vet was so confused by this, she asked another vet to preform the same test and Tiki pretty much just sat there wondering when they were going to be finished. Hopefully the pain is starting to go away and the antibiotics must be working. The local vet is phoning the U of I office tomorrow and hopefully they can suggest more local tests. If U of I has no other suggestions for local tests, we will need to take Tiki to Champaign, Il to have a bone biopsy, to test for cancer.
