A nice 6yo gelding, brought on quietly. Been 2/10ths lame for about 8 weeks now. Has had 2 weeks box rest on bute, no change. Been seen by own vets - plus 2 days wih the consultants. Nerve blocked, x-rayed etc. Nothing! Physio has checked him out thoroughly - couldn't find anything. So he's coming home today to try another 2 weeks box rest! It's his near hind - that's ALL we know. Any ideas?? I've NEVER had a lame horse before that didn't get better, or worse, or who showed NO indication of what the problem was.
