I'm catching up on some questions sent to me recently and I had a couple related to what my experience has been with horses that are tying up. I hate to say it all depends but, "It all depends".
It's fairly rare and I have only had two horses have such problems. Both were sporadic issues with one simply going away and the other having to be treated over a longer period. Injections of muscle relaxers were involved, as was a new diet. I have no understanding of today's racing medication rules related to this condition and hope I never have to research them again.
Of course, personal experience and opinions are generally irrelevant anecdotes. My advice is to research studies or data, and I will refer to one 2010 Equine Research Article written right here at the University of Minnesota. I found this valuable in trying to understand the condition a few years ago.
