Thanks, I feel better now :)
Yeah she's gets hard workouts every time I ride her, which is about 6 days a week.
I'm thinking the bitter cold has something to do with it. She was on stall rest for most of the summer (grr, colic and then cut up her leg) and never got stocked up.
I'm thinking I'll just leave it alone and not wrap it or anything. It goes down and it's not making her stiff or anything. Granted, she's a firey 8 year old thoroughbred.
