| I have a mare that after a work out today had muscle tremors on her chest and shoulders. I rode for about 30 minutes. To be honest she wasn't herself. At the beginning of the ride I didn't notice much but after trotting and then starting to lope she seemed very anxious and bracey when asked to lope collected. She sweated more then usual and seemed like she got a out of air faster too. Just not like her. I decided to get off because I became concerned and noticed she had some strange muscle tremors going on her chest and very lightly on her shoulders. She never seemed to be in pain or reluctant to move but just anxious and bracey. I am at a loss. I called me vet an she was concerned but not enough to have a complete explanation for what happened. She isn't sure she even mildly tied up. I am of course very concerned. I have a video of the episode in the YouTube link below https://youtu.be/rL2wEKH1Wic I am going to have her seen and probably tested if they think it was actually an episode of tying up. What is your thoughts and experiences? I have no experience with tying up. The only reason it crossed my mind when I saw it is I saw a friends hypp horse have the same looking tremors before an attack.

| *almost there* - 2018-05-01 11:39 PMFrom a personal perspective, sounds and looks like an episode of PSSM type 1. She is 12 this year and never had anything like this. Can it just start happening to them? I've had her since birth and raised her. She's been on the same feed and hay since she was 2. She is also my good horse and has been fortunately very successful. The only change is the last year and a half she has been rehabbing from an injury. She spent 6 months in a stall and now for the last 8 months has been getting put back to work. My latest lameness evaluation was last week. She was sound but thought to be "muscle sore"... Which surprised me.

Location: Lost in the swamps | From the look at the video and location, and type of the movement. Did you see if the movement matched her pulses?
It really looks like the large blood vessels in the neck pumping blood. More than a tremor. But Possible Pinched nerve, strained muscle? We have a hypp horse at the farm and her tremors looks very different but I can understand every horse is different though. I would have your vet check this out and if you have a suspicion of hypp, the test is cheap and easy. We didn't know the horse we have had hypp till testing. We knew she had horses waaayy back in her linage with it but didn't think it carried out that far (6generations) her two sires were not on the lists of hypp carriers. But she surely tested hypp n/h.
And it wouldn't hurt to check into pssm as well.

| Could be a magnesium deficiency. I had one that had mild muscle tremors now and then, magnesium ended it. And I’ve had several anxious, muscle tight horses that were helped by magnesium, especially in the summer and fall when it’s hot and they are sweating more. They lose magnesium in their sweat. |

| My mare did this for the first time as well, looks exactly the same. Only happened once but had her tested for PSSM and she was neg. But I had started her on small amount of whole oats about 2 weeks prior. Not even one cup 1x a day. My vet said some horses are extremely sensitive. Stopped the oats and never happened again. |

| Thanks everyone for the responses! I'm having blood drawn to have a cbc, chemistry and fibrinogen checked later today. She doesn't have any impressive in her blood lines so I'm not worried about hypp. So maybe I'll look into having her tested for pssm once the results come back. |

I'm from the north pole lol. Wisconsin. I don't blanket my horse so yes she still has her winter hair. She could have gotten over heated because it was warmer yesterday being 70. My biggest concern was she was very anxious and bracey during my ride. Last week we tested her vitamin e and selenium levels because she seemed "muscle sore" during her lameness. But like I said passed the flexion tests. The blood results haven't come back yet. |

No wonder she still has alot of winter hair  , Like someone else said I would start her on magnesium and see if that helps with her being body sore.. She to me looked like she was a little over heated in the video,, do you have a full body video of her doing what she was doing? Just us updated on what the Vet says, I'm curious now.. Good Luck with her  |

Yes, it’s generally when a young horses work load gets heavier or a horse is coming off of an injury that requires stall rest/minimal activity that pssm rears it’s ugly head. |

very interesting and obviously she's coming off of a long while of inactivity. She has been started back slowly but who knows. It's worth making note of. |

I don't have a video of it on the rest of her back because I had to saddle on. I saw it just faintly on her shoulders too and I thought at first maybe it was her pulse like someone mentioned before in this post but it was even after her respiratory rate started to slow down. It didn't seem like it was in uniform with her pulsing cuz it was doing it in different rates |

| ok so now I'm wondering if it is her pulse and I am overly observant on something that is nothing. I was told to lightly lunge her and I did then tied her to the trailer and saw the neck movement again. It still doesn't explain the muscle movement I saw on her shoulders and why she rode so crappy yesterday. This is sort of like when you think your horse is off so you look at them move and you start to begin to not know what you see anymore. |

Sometimes we worry to much and sometimes not enough, but shes your horse and you know her better then any of us, so just go with your gut feelings and keep an eye on her and talk with your vet more about what you feel may be going on. |

Very well could be PSSM2. When they are positive & asymptomatic, but then have an injury, surgery, etc, they can go into negative nitrogen balance and symptoms become much worse. And PSSM2 is more likely to show up at a later age vs young. As advised above, I'd join the PSSM Forum on FB and investigate. |

Muscle tremors. Mild trying up episode?
