Long story short, A friend has a stallion she aquired recently. I don't know his exact past, just that he was successful on the track, Suffered a sessamoid fracture that ended his carreer, then at some point had "shipping fever" that progressed to a very severe case. The horse is a fighter, and the vets saw that and were able to save him, after a very difficult illness. At some point they determined he needed to have his chest cavity drained, so two holes were made, one on either side, through his rib cage.
One side healed and is just indented, the other side has a small hole still open, constantly draining yellow pus. He was put on antibiotics before, which did nothing. Friend had him on natural antibiotics - still nothing. He has been in my friends care for 2 months now, he is fed the best, wound cleaned daily, blanketed, etc.
Other than the draining wound, he is 100% healthy. Great coat, nice weight, energetic, normal temp.
My friend has an amazing vet, who is currently working on the problem, but it has him stumped as well.
What could be causing this? Its seems unusuall for a young, otherwise healthy horse to not heal? Maybe a foreign peice of something in there?
Has anyone even heard of anything like this?
