No judgement on the slow response. My girl flared in June and didn’t fully heal until December because we treated as mud fever as well.
I actually got so frustrated with the whole ordeal in the fall that I fell down a rabbit hole trying to figure out what the heck was wrong with her legs. I found leukocytoclastic vasculitis and showed it to my vet. So that was probably October that we started Dexamethasone and consistent 24/7 wrapping. Also forgot to mention don’t excessively wash or put anything on it at all. It doesn’t need anything else to piss it off hahaha.
I figured out the alfalfa down my rabbit hole. I found all the research about photosensitivity with alfalfa etc. There was also a vet who was heavily involved in the vasculitis scene and he strongly encouraged no alfalfa for these horses. I followed all his suggestions and I give credit to his advice on why I have been flare free for so many years.
I will have to see if I can find his information, it’s been quite a few years now and I can’t remember his name
