Luckily, when he palpated the hock, he changed his thoughts on the hock. It turns out to likely be a hernia on the tendon sheath. Gem isn't lame or anything, so Doc says we just need to watch it and do nothing at this point until it seems to be bone related. For now, it's a blemish and nothing more.
What a relief!
I'm really missing horses. It's been a rough month for horse-time between family vacation and the winter weather moving in. This weekend is our last group lesson, so I'm looking forward to a day with Gem and spending time talking about horses with my horse friends.
