Ok, I just got in from the barn, so here's an update. Scout's sheath is the same as it was at 9:oo last night. The swelling is "soft," and Scout does not react at all to my examining it, it doesn't seem painful. However, he is now lame in his back end. His stride in his hind legs is uneven, and he is reluctant to disengage his hindquarters or turn on his forehand. No hiking of his hip, or head bobbing. His right hind hoof, the same side as the swollen sheath, is slightly warm in comparison to his other hooves. The farrier was out yesterday, and he had his shoes pulled and a trim, and is currently barefoot, to be reshod when the ice melts.
What do you all think? Is the lameness a coincidence, just tenderness from the recent trim and shoe removal (my current suspicion), or a part of the swelling issue?
@ Goldrush: Scout is around 8 years old, I don't think it's an age-related thing, but common in older horses doesn't mean unheard of in younger ones. Dad's going to take a look-see when he gets back from work around noon, I'll probably call the vet after that. Thank you!
