Okay, here it is in a nutshell. Tuesday I found my horse had a partially off twisted shoe on his left hind. He was standing on the clip and the nub of one of the nail ends. I took the shoe off and checked for punctures. Nothing. Wednesday the farrier came out and put a new shoe on. Everything appeared fine, but my horse was very fussy with that leg. He kept pulling back like he wanted to put it down. Today I went to clean his feet and found heat in that leg from bulb and about 6" up the leg. No further. A little swelling, but you'd have to be looking for it to see it. There is a little scrape near his coronary band that he got about a week ago which I have been putting ointment on, so I don't think that's a factor. I hosed the leg, iced it and wrapped it keep it from swelling more, but am a little baffled on what he did. The hoof itself is not hot, and this farrier is very good with TB feet, so I do not suspect a close nail. I don't feel any pulse in the bulb, so that's good. I'm thinking maybe he was playing, spun around and twisted his ankle, thus the twisted shoe? Any guesses or suggestions for treatment?
