After listening to what we have went thru since Sunday - the stall rest, cold hosing, wrapping, and Bute - she believes Riva most likely whacked her front leg with her back hoof either when ridden last Saturday or during turn out. The swelling on her leg is gone, no heat, moving like normal.
The vet said to start with light turn out and light riding - ease her back into work. I can handle that plan. So relived that the tendons are not damaged.
