My mare's chest got pinched here about a month ago and a little bump about the size of a ping pong ball pop out. Its soft and it just looks like a sack of fluid and doesn't bother her one bit. It has gone down a little bit in the past two weeks. I had someone come over to the barn and say that to bath it in hot salt water and that if I don't that it will turn hard and harm her. (he has been known for not knowing anything about horses and he always tries to scare me into selling my horse to him) Just wondering how much of this could be true and if there is any home remedies out there. I tried to find some dmso but I can't find any around here.
