So my question is can start riding her, say, in week (may be even just bareback)? By riding I mean something 15-20 mins per day with mostly walk and some light trot. She's young, so I really don't want to do any breaks in riding unless it's really something I must do. My neighbor said it's not that big deal, but I'm still concerned.
And yes, I personally worked when I had pretty big hematomas as well as started exercises shortly after cut in joint and the cast was removed and so on. But I don't know whether horse can handle it or not. :)
