Just what I've found from Google. I haven't read them all properly and fully digested yet mind you!
The latter being not quite-so-relevant but still lots of interesting information out there. Also, I thought this thread on EE was rather timely:
Best wishes to this horse and his owner.
I do feel perhaps I ought to have called the vet sooner but mercifully it seems Quadi should make a good recovery, although with an(other) issue I will always have to keep an eye on. Frankly, with all the little grumbles and niggles going on in his feet that we discovered as an aside, it would only be a matter of time before he becomes permanently unsound. So if we come through this and I have a horse happy to be back in work, every day's a blessing. If that sort of pedestrian statement doesn't make anyone gag *lol*
eta: I can't get links to work, you'll just have to copy and paste!
