Well, he did seem to improve after the anti-inflammatory/antibiotic shot, but despite the care taken by the Singing Shearer, who was gentle with him when he was shorn on Friday, he's back to square one with the limping. I've had another close look at his leg now the wool is off, but I still can't see anything visibly wrong with leg or foot. If I squeeze the leg gently, he flinches when I get to the inside of the hock (where the inner elbow is on a human), so I'm still thinking it must be a sprain. He grazes with the foot raised, but can put weight on it if I lift the other back leg.
My question really is how long should a sprain last? (I know when I sprained my ankle I limped for over a month). He's been limping for ten days. Should I just be patient, or ask the vet for more anti-inflammatories or suspect something else? He's grazing fine, seems happy enough - tries to pogo about with the others and no teeth grinding. Any thoughts gratefully received.
