I have a 3 yr old TB that came in with some localized swelling right below the knee. No pain, no lameness just the swelling. I wrapped it, hosed it, buted it thinking it was no biggie since it didn't bother her. The swelling started to go down but expanded to have slight swelling about 2 inches long running down the tendon behind the knee. Still no pain, no lameness, etc. She was a little stiff and didn't want to totally extend the leg at the trot but I think that was pulling from the swelling as weight bearing was not a problem she just didn't want to extend it and ended up very slightly shorter with the opposite foreleg. My vet is giving me the run around since she's not in any discomfort and he's busy, he said don't ride her til he gets there. She's currently in 24/7 turnout, she doesn't do much occasional trots and lopes but again 100% sound and you can only feel the slight difference in stride on the circle under saddle at the trot, no other gait and she works out of it. My question is, does anyone have any experience with this type of injury? Should I just let it heal and strengthen with turnout, some light trot sets to speed it up? Any supplements/feed/maintenance I can do to help it? Bute brought the swelling down to where it is now but it's not gone and after a few days at 2g, I went to 1g and after a week discontinued it as she has zero discomfort and it had stopped making a difference in the swelling. Any advice, info, etc you have would be greatly appreciated. I've dealt with severe tendon injuries but never something this odd with no lameness.
