The Poneh and DH had an incident while on a trail ride… Poneh slipped on a wet bridge and did the splits behind. DH called me frantic, but other than a little bit of general stiffness poneh was sound and happy. A couple of days later I find one hind leg grotesquely swollen, I mean fully stovepiped from about the stifle aaalllllll the way down. My trusted lameness vet was out at the barn on a call for another client, agreed to take a look at poneh, and immediately diagnosed cellulitis.
Fast forward about a week. Poneh has never been terribly off on the leg and the swelling responded well to meds and cold therapy, so we go back to light work. After a couple of days I start noticing filling in the leg again and poneh is getting increasingly uncomfortable. I also find a very strange, HUGE lump in his groin area (bigger than my fist). I call the vet who is perplexed, but agrees to come look at it asap. Turns out he had a severe tear of the gracilis muscle (the vet said he very well might have a gait abnormality after it healed) that had created a huge hematoma in his groin and caused the swelling in the leg.
He never really came back 100% from that injury, though I think it had more to do with his advanced age and generally declining health than the injury itself. He did come totally sound on the leg. I don’t fault the vet in the slightest… it was a super strange injury, and knowing the horse and the situation, cellulitis made sense. If anyone is at fault, it’s me for not taking DH seriously when he said he thought his Poneh might be hurt
