My horse had been acting a bit odd for about a month-for instance he felt like he wasn't all with it when being ridden and breaking down his stall door without breaking down the stall guard (all he would need to do is push and he would be free, but he didn't) and then his striding at the canter was off so I called the vet and he said to just put him on bute for two weeks and see if it clears up.
After about a week and a half my horse seemed to be back to normal, but then the next day I was leading him into the barn and he stopped and just started shaking uncontrollably.
It started with him chewing like he had just been wormed and then it looked like he was going to swallow his tongue. He had his head bent around to the left and his jaw was set crooked. This went on for a few minutes and then we walked him out and he was fine. By the time the vet came out he was back to normal, but because he was still off in the front, we figured he had just been writhing in pain due to a pinched nerve or or pulled muscle in the shoulder. I then went back to giving him bute, stretching out his legs, and rubbing absorbine on his shoulder.
Once again after two weeks he appeared to be normal and we were getting back up to our usual amount of work and then this morning my friend who witnessed the first attack was riding him back from the creek (nothing more than a walk) and he backed up and started shaking again, but this time only the left side of his face was affected.
Like I said before the vet HAS been involved and he did test NEGATIVE for EPM. Has anyone else experienced anything similar?
