Grace, I agree that it would be a good idea to have the vet look at her fetlock. Since it's been so long and there's still puffiness, it would be good to know for sure whether there is anything to worry about. I hate puffy legs - there is so much potential disaster lurking beneath the skin of a horse's leg and the degree of swelling isn't really a reliable predictor of whether or not there is a big injury or a small injury.
If you get the vet out, be sure to ask whether wrapping would be advised. You can use the Sore-No-More under wraps - it's one of the few that is allowed with wraps. The reason I am thinking wrapping might be a good idea at this stage is that sometimes the swelling alone is enough to cause problems, from allowing the veins and structures to distend with fluid, and proper wrapping keeps the swelling under control. Wishing you the best of luck in getting this pesky problem cleared up!
I spent all morning at the barn, by myself, it was glorious! I sat in a chair in the sunshine out in the pasture and let Kes much on the grass for about 30 minutes. Cleaned out her stall, groomed her and fed her lunch. She's starting to put on some weight, and is looking pretty good!
