Hi, my pony has a swollen fetlock on her front leg. It is mostly swollen on the back of the fetlock and she is limping badly. There is no heat in the swelling. SHe was let out to pasture with the other horses to get her out of the mudd in her pen and it got worse. Am I right in thinking that letting her have stall rest will fix it? It went back to what it was before the pasture yesterday. anything I can do to make it heal faster?
