PSSM, any experts?

Type 1 isn't common in pure bred welshies, but then it wasn't thought to be in the new forest ponies either until about 2 years ago.

I don't think there is every any harm in following a PSSM appropriate diet and seeing how they go. Off the grass (weeing a lot can be a sign of EMS as well - body getting rid of sugar), low NSC diet and vitamin E. I know a few people with diagnosed type 2 horses who have found adding essential amino acids really helpful.

Worming up to date? Someone emailed me from the PSSM forum to say their suspected PSSM case was actually riddled with tapeworm.

Are you in a tick area? Lyme is getting more common and can present much like a myopathy.

I've mentioned on another thread today that gel injections into my mare's hocks have made a huge difference whereas steroids did nothing. She was investigated for SI problems and although they found a tiny arthritic change and injected her, I'm pretty sure her problems were hocks related. I can now do hind leg stretching without risking my life and so can only imagine how sore she must have been.
 
Thanks for replying SEL, I know you're knowledgeable on this subject!

Wormed 2 weeks ago.. with Equest Pramox.

No, fields fenced in a way we rarely get a tick even with the dogs

Glad to hear shes feeling better, great news. We have x-rayed absolutely everything, stifle and hock steriods made no difference. The only thing we haven't looked at is SI. On flexion tests he isn't really any worse, he isn't lame. The second opinion vet described it as being 'uncomfortable behind' rather than lame. Its just strange how he almost seems worse since being on more grass..
 
You can test for the type 2 variants here https://www.centerforanimalgenetics.com/product/pssm-panel-pssm1-and-pssm2/

There's a big study going on at one of the US universities to determine what these genetic markers actually mean in practice. They were hoping to get 1000s of horses signed up but Covid turned up and curtailed plans somewhat. Its not cheap to test but might give you some answers

Oh very useful thank you. I've ordered some Equimins Vit E, my vet agreed to test muscle enzymes when hes here next week and depending on the results test for PSSM?
