Hi, just got bad news from the vet this morning and just looking to cry about it a little bit and any insight anyone can offer is welcome. I’ve had my horse (13 yo QH mare) for a little over a year, I spent like most of 2021 trying to diagnose her being not quite right and found that she has very bad arthritic hocks, injected those, and then later on in the fall after nerve blocks and ultrasounding discovered a very small tear in the front left high suspensory.
She wasn’t ever super noticeably lame in the front except for on certain footings, never noticed a ton of swelling or heat or anything, so the vet speculated that it was an older injury and we had no idea how old.
From Oct - Dec she stayed on 24 hr turnout “rest” and then we re-ultrasounded in December and found that the lesion was 50% healed, so the vet instructed me to start tack walking her, 3-4 days a week, 15-20 minutes at a time, straight lines and hard solid surfaces only.
About a month into that, I noticed a little bit of heat in the left front suspensory area, contacted the vet and after about a week of icing and wrapping when the heat didnt go away, I had him out for another ultrasound. He found two tiny new lesions on the suspensory in addition to the old one, that looks largely unchanged 
I’m definitely going to move forward with shockwave therapy, he said that she’s not really a candidate for stem cell because the tears are just too small.
He also said that I need to start restricting her turnout, which is really stressing me out. She’s been on 24 hr turnout since I bought her, and with her hocks as bad as they are I think that’s definitely best. I’ve only had to keep her in a few times since I’ve had her, but she definitely reacted with a lot of stress and anxiety each of those times. I’m sure once she gets on a routine of whatever stall situation we figure out she’ll do better but it’s the process of figuring out that routine that’s going to be difficult. I still have to talk to my BO, who I’m sure will work with me on figuring something out for her, but whatever it is it’s going to be difficult and expensive for me.
Plus I’m also just confused about why her turnout has to be restricted now when the only thing that’s changed between the last ultrasound and this one was the tack walking! The vet seemed to think that the controlled walking wouldn’t have done this, and she must’ve done something in turnout instead. But I know that she does have a lot of compensatory movement from her hocks, and the right hock is the worse one, so it would make sense to me that the riding put additional stress on the front left suspensory - even just at the walk.
The vet said ideally I would keep her in and only turn her out for 2 or 3 hours a day for a couple of months… I was like “ok so what if I can’t do that” lol and he said at least try to keep her in at night and turn her out daytime only. This is probably doable but I still have to talk to my BO.
I’m obviously going to do whatever is best for her but I’m just really stressed out about how I’m going to make it all work. Running out of money and hope that I’ll ever have the horse I thought I was getting when I bought her 
) There was no way he would tolerate stall rest when all the other horses were out. We also used some chemicals to keep him quiet in the earlier stages. The closer you can stay to her normal routine while still restricting her activity the better.
