Hi everyone here’s some background on my girl: she’s 23 and we’re riding 2nd level dressage non competitively (schooling some 3rd with clean changes). She used to be a hunter in her youth, and then in her teens I transferred her over to full time dressage.
She had had about the last 2 months of intermittent work due to various injuries - hoof abscess, then she clipped herself, then a cut cornea, then a large gash on her fetlock. She’s sound and back to regular work and turnout (12 hours out 12 hours in in a 12x22 stall.)
Within the last week she has developed some muscle soreness in her SI region when palpating. She had her SI injected exactly a year ago via guided ultrasound. She palpated sore then but was much worse, and the soreness went all the way through her lumbars. She lost almost all of her back muscle when that happened. The biggest culprit at that point was that her movement and work ethic was drastically different: poor canter transitions, very hollow through her back, and very short steps. The injections solved all of those problems. At the moment, we have none of the movement issues.
It seems like it could be the start of her needing her SI injected again, but I know generally they don’t palpate sore. Could it be something else? Could it just be that she’s back to work and using those hind end muscles differently than she has for a couple months? I will absolutely get my vet involved, but at this time they are doing emergency calls only.
Any tips on how I can relieve these muscles, or anyone have a horse that palpated sore and indeed just had arthritis in the SI? People that have had SI injections- how long have they lasted for your horse?
