My 16yr old Thoughbred has been getting these wind puffs that come and go for about 2weeks now. It started with just one, when I asked my trainer about it she said that windpuffs are nothing and not to worry about it. They've continued to come and go, they've gotten bigger and he's had multiple wind puffs at a time. These are all accuring on his right hind, which we've had some issues with in the past. Now he's lame on his right hind, and has 3 wind puffs. 2 just below his fetlock and 1 just above it on the inside of his leg. Could these possibly have anything to do with his lameness? Does anybody know how to treat them?
