Suspicious swelling

[duke7]

My horse developed a windpuff in her right hind leg roughly 2 months ago, right above her fetlock on the side. It caused some swelling in her pastern, but eventually went away after giving bute, cold hosing, poulticing, etc.

Approx 2-3 weeks ago I noticed her pastern started looking stocked up again, but she was not lame on it and it would go down with work. I gave her a few doses of bute, did some cold hosing and hoped it would go away. It still continues to swell up at night, (or when she is standing) and I don't know why. Could it be because of a soft tissue injury and not the windpuffs?

I don't know if I'm overreacting here, since she's not visibly lame to me, but she does tend to rest that right hind leg a LOT when standing.

Advice would be greatly appreciated!
Thanks

My horse has windpuffs in both hind legs. If he has too much time standing around and not going out or working, like right now with all the bad weather, he will swell up until worked. If your horse is not lame don't worry!
