@farmerman,
Arella, I used to cure my last horse, Angel, by putting a compress using (?) I cannot remember that blue lotion rather heavy on her leg from ankle to 'knee.' Then I'd wrap that (tight, but not too) with cling wrap, then a heavy cotton wrap over the cling wrap. That stuff really heats up in there. One of my trainers taught me how to do that. Works to heal everything! Unless her injury is farther up into hip.
I was having some trouble with cute little Angel. It took a long time but I found out this couple was purposely injuring her, or riding her, gosh I just don't know. I just took care of her, didn't have the time to even wonder why these odd injuries were occuring. All I can think is they wanted her for their little daughter. We finally put her in another barn without saying anything. Unless I truly knew, and had evidence it was them, that's a terrible thing to suggest, or ask why about. One of the worse experiences I've had in my life.
Sometimes boarding stables don't have the best of people working with the horses.
