Thanks. I'll look into that. What still has me perplexed though is that she seems to only show signs when she's under duress and this only just started this past fall. Wouldn't she have shown signs all along when working? I've had her since she was 10 months old and have trained her exclusively myself...she lives at home so I don't miss out on much.

Well besides blood testing and getting a vet involved, there isnt alot more to do except test for HYPP that I can think of. If she is crossed with QH I would absolutely test for HYPP. An N/H horse could indeed possibly show small symptoms as you describe although im not sure the sweating fits. But if she is N/H, you NEED to know. The test is cheap and easy and one thing you can rule out.

PSSM I believe needs a blood test after work to check for muscle damage. I would call your vet and bounce some of this off them as well. Its good to check into things like this and stay ahead of the game. You just never know. Better to nip it in the bud if it is something you can control with diet.

Stress & diet are the biggest triggers Horses can go long without showing anything & then bang one day symptoms can appear having the right trigger set them in motion

Thanks you guys...good to bounce stuff off others sometimes. I'll pull some hairs tomorrow and get going on this. I'll let you all know what I find out!

GL! I hope it turns out to be nothing or just something simple :)

While you're waiting though, I would take your horse off of any potassium-laden things, including alfalfa, as this triggers muscle twitches in HYPP positive horses. Just a precaution :)

Might be PSSM! I have a PSSM horse who was perfectly fine until she wasn't. We did endurance for two years even. Nothing. One day we went on a little trail ride and BAM. Full prone tie up. Almost killed her.

We thought it was a one-off thing. Until stuff kept happening. This time it was a lot like what your horse experienced. We were in a stressful situation. She started to tremble and sweat. She would short stride in a back. This happened a couple times. These episodes weren't exactly "tying up," but it wasn't something I took lightly. I called me vet again and we discussed how this could be a chronic problem. The vet said it might be PSSM, probably Type 2. My horse had actually been showing signs her whole life. She couldn't canter, had muscle atrophy on her top line and hindquarters which increased the more I worked her, and had a mysterious shifting hind leg lameness. Occasionally, she even had stringhault like symptoms.

We changed her to a little low NSC grain and added fat, supplemented vitamin E and selenium, kept her turned out 24/7, and put a grazing muzzle on when the grass was green and sugary. She's a whole new horse now!

PSSM type two can't be found with a tail hair test. Only type one can be tested for that way. Type two has to be diagonosed with a muscle biopsy. I didn't opt for the biopsy. It's expensive and a little invasive. My mare was diagnosed based on her response to treatment.

Thanks for the info Brighteyes. That's been the hard thing to figure out with my mare, that she hasn't shown any major signs until this past fall and we've done a lot of long trails, camping, hunter paces etc.... I plan to cover my bases and do the hair sample test plus call my vet.

Sent off my tail hairs the other just waiting for the results!

I would second the Hypp or PSSM possibilities, especially if it is becoming more and more frequent...keep in mind sometimes it is easier to treat the sypmtoms to get your diagnosis, like brighteyes said, just changing the diet and environment and seeing if it makes a difference can be less stressful for horse and person :)
