Hind splint in my jumper- please help!
I have a 12 yo warmblood mare that I have been showing in the low aos since the summer. She is truly incredible. She has managed to pop a splint on the outside of her back left leg. This must've happened recently, the groom just noticed it but it is rather obvious now if you look at it.
She's not lame (at least as of yesterday). I jumped her and she was sound and willing. We ordered Splintex I believe it is called.
Any input on this? Should I be worried?
