nerve blocks different at 2nd exame??
I have a 20 year old AQHA that came up lame right after we purchased him 4 weeks ago. He vetted clean at the PPE except for slight response (1) on right hind fetlock during the flexion tests. Had the vet out right away. Found a small drainage track on right front, block to sole got 60% soundness, block to the back of the fetlock around to top of hoof got 100%. X-rays showed some navicular changes but since the horse didn't show other side lameness at block the vet wasn't sure if those findings were within normal for age. Cleaned up drainage track, shoed fronts with a wedge shoe, bute for a few days and a week rest. Horse seemed better but he is still off so had vet out today. Pulled wedge shoes since vet is convinced they would cause dramatic improvement if it were navicular. Redid the blocking of the navicular bursa and there was no change in soundness so pretty sure it is not navicular. Blocked the rear of the fetlock and around to the front of hoof and still no change. Did flexion of the fetlock and then the knee and neither made the horse worse. At that point vet needed to get to next appointment so we scheduled for him to come back to do more testing. The only other thing that was different today was that the horses right rear fetlock was swollen like it was stocked up. Has anyone had anything like this?
