I have a 9yr old AQHA mare who has started having lameness issues. Started out 2 months ago I noticed she was favoring her right front leg. She had swelling in her fetlock. So I kept her stalled and kept stress line 2000 on it and buted her for pain. Few days later an abscess drained at the outter corner of the Cornet. She started recovering and a few weeks later she developed swelling to the left hind leg and started favoring that leg. Same thing happened. Few days later she had an abscess that drained out of the outter corner of her cornet. So today I was looking forward to riding her again. Pulled her out of her stall and her left front leg is swollen with heat to it. Her left hind leg has slight swelling without heat. I'm not sure if there is some sort of illness or disease process that causes multiple abscesses and swelling. I would love feed back and ideas of how to treat her.
