Re: Unusual Problem

It sounds like your horse is tying up.  This is like when you get a cramp in
side from running, but it affects the muscles in the back and hindquarters.
One speculation as to the cause is when you ride hard one day, rest the next
but still feed the same food like grain, then ride hard the next day.  Another
guess is that when you pour cold water over the hot muscles in dry regions.
You can most likey look this up in the Vet part of the Horse Forum.
