I'm looking for any help/advice/thoughts to figure out what is going on with my mare. I had this mare chiro'd the beginning of July. The chiro said she had a pinched nerve in her left shoulder and was out in her right hip. At the end of August, I came home from work and noticed she was trotting in her pen but was slightly favoring her right hind. I had ran her a few times before this and had noticed she wasn't running the times she normally had been. I took her to the vet and he x-rayed her hocks and injected them on August 30th. He didn't notice anything alarming in the xrays but felt that is what she needed. I gave her an entire week off and she got better for about a week and then the slight limp was back. I took her back in on September 13th and he injected her stifles. I gave her another full week off and the limp never got better. Took her back to the vet on September 23 & 24. He xrayed and untrasounded her stifles and nothing looked wrong. He nerve blocked her pasterns and hocks and the limp was still there. He palpated her and didn't feel anything wrong with her ovaries or SI. He had me put her on a months rest. I did take her to the chiro 3 times within those injections and he said she was out really bad in her lower back and each time he put it back in it seemed to slip back out. I have done magnawave treatments every week since September 26th and she seemed to get better for about 2 weeks and then the week of October 18th she was horribly sore as you can see in the videos we took that day. I believe she is in heat when that video was taken and there seems to be a pattern of her getting way worse when she is in heat. The videos were taken on Friday October18th and by Sunday the 20th she was a lot better than she was in the video. She has not been ridden since the end of August.  I'm totally confused as to whether it is SI, Ulcer Related, Hormone Related, Back Related or Muscle Related. She is going back to the vet but hoping maybe someone has experienced something similar that can help give us some direction so we aren't just poking around in the dark.

I would x-ray her back/SI area, see if there's something going on there. I just had one that we thought just stifles were the issue & then x-rayed her back to find old fractured vertebrae & KS, so you just never know. Discuss with the vet the situtation with the chiro and the back issue not resolving. Hope you can find answers, I spent over a year trying to figure mine out & ended up making a 12 hour round trip to go to specialist for my answers.

Which specialist did you go to? That has been the frustrating part is that I didn't feel it was her hocks or her stifles and that it was farther up but my vet wanted to start with the hocks and then stifles. He is a very good lameness vet and is well known but even after I told him what the chiro said he was still focusing on the hocks and stifles.

awe poor baby................I would also think about a second opinion................thats a significant limp.......ya never know fresh eyes might help............

Oh how I remember the days. A $25 hair analysis would have saved me close to $5000.00, plus a whole lot of sleepless nights. Here's the story of my 7 yr old mare. She never limped, just felt "off" in the rear end. Lots of chiro visits and several different vets later, still no solution. Injected, hocks, stifles, SI, each multiple times, changed diet, back shoes on, back shoes off, 3 rounds of EPM treatments, Regimate, the latest and greatest supplements, ulcer preventative and then ulcer treatments. Nothing ever helped. She never even took a gimpy step, just felt off. Not noticeable when you watched her, but I could feel it. Times slowed down, hands hurt when the run was over, and Resting B---- Face didn't even begin to describe her new, permanent look. I was ready to throw in the towel. Then I started reading up on hair analysis. What's another 25 bucks! I bagged and mailed it. I stuck a piece of paper in the envelope with my phone number and my mare's color and age. Nothing more. I received a phone call about 4 days later. Before I get to the good part, let me say this, 3 years earlier, my mare had stopped sweating. This went on from July to September, which was when we had our first cool night. Sweating issues never returned. So, fast forward 5 years. Hair analysis results: Hypothalamus and front right Bursa sac. She told meI could put her on some supplements, OR, I could get my farrier to set her at a 56-degree angle (I think that's correct). I was already scheduled with the vet, for more injections, I'm sure, so I wanted to see him first, then contact my farrier. I didnt tell the vet I had the analysis done, I only asked if we could do flexion tests on her front end. Lo and Behold-- I think I cried tears of joy. She limped off. Head bobbing and all. Yep, it was her front right. Vet did a nerve block, she didn't limp at all. The next week, the farrier came. We did a lot of talking, measuring, scratching our heads, and watching her move. I had a lot of faith in my shoer, and after he left my house, I finally started to feel a little relieved. All that time and money, wasted. I should have never let a vet inject her, but I was at a loss. Lots of valuable lessons learned. It's been 3-1/2 years since I pulled those 10-15 pieces of hair from her mane. She's made a super nice, gritty/competitive barrel horse. I knew she had so much potential, but all those issues started during her year of exhibitions. I had never been a day of my life without a horse, until 2 years ago, when I sold her. I went through so much with this mare, At the age of 50, I decided I had had enough stress. Bass fishing is pretty relaxing!

I don't understand why he only blocked to

the hock ? Why wouldn't he block the stifle pouches ?

i would X-ray right stifle first. I would ultrasound it and make sure the meniscus looked normal (needs to be a vet that is good at u/s). That actually looks like a meniscus problem.

The problem is in her right hind, not her back.

I have one that moves EXACTLY like this and he has a collapsed stifle. I had four vets miss it on rads, the last vet caught it immediately from looking at the rads. So, my point is rads are only as good as the person reading them. I'd be getting a second opinion.

Thank you for the advice. That's was what I first guessed when I took her in. She got kicked on one stifle when she was 3 and when she was early 4 she slipped on the ice and landed on the concrete pad around the waterer on the other one. I took her in after that one happened and he xrayed it but didn't see anything that she hurt at that time. He did xray and ultrasound them both and injected them on September 24th with no improvement so I have been at a loss. Would the injections have helped at all if it was a meniscus issue? 

I'm sorry, I missed that the stifles were xrayed and u/s.. 

considering that, I would want to block directly into the hock , joint by joint and see what happened. I had a case very similar to this last year.

i know it's not likely but did he put hoof testers on the RH foot ?

Hi there. Can you tell me where to send the hair sample to and what the process is? I would up for trying that for $25. I've already spent a couple thousand.

Yeah I'm wondering if he missed something. She did have both stifles injected though and it made no difference. What did you end up having to do with yours for the collapsed stifle?

Yeah he did test her hooves but she didn't show any soreness there. I think he did block directly into the hock plus she was injected in the hocks 3 weeks prior to that as well. 

Yes, I noticed he injected the hocks and

she got better for a short time. If she responded for a short time to the hock injection and he doesn't see any problems in X-ray is u/s the soft tissue around the hock (like media collateral) and high suspensory. I've seen them lame  from a medial collateral tear, not from a suspensory but if it was fresh it's possible . Medial collateral would be where I'd look first

He's a big, beautiful pasture ornament.
