On the front of my mare’s front feet, the back of her ankles, she has a little bump on each leg. It slightly squishy yet firm, so I suspect there is some fluid in there. I have researched it a bit and think it maybe windpuffs, but I’m not very familiar wth them. She shows no sign of soundness issues. but they “bumps” are new I believe, or I’ve just never them before. Thanks
