This sounds like what we went through 1 year ago almost to the date with one of our miniatures. She is only 30" tall and our best jumper - her HOF would be in reach in the next show season (2013). Our miniatures all have individual stalls they eat in then are turned out into groups of about 6 where they can come and go from the stalls into dry lots. Lots are clean - pasture when they go out is clean - basically what they can get into without me knowing is only what may blow over from the tree line before I get to it. I am home during the day and can keep an eye on things. She was fine at 8:00 breakfast, was turned out with her group around 11:00. I went out at 12:30 to let out another group and she was fine - last place I saw her was laying in a stall in front of the fan with her group standing over her. One being 36.5" and wanting to move up the pecking order. We went out at 5:00 to do supper chores. She came in from the dry lot with no coordination in her hindend. She walked like she was drunk. Her gums were very pale and her heart rate was high. I called our vet, use a local teaching University, then decided to just get her to the clinic. Something toxic was all I could think of, although I had no clue how she'd get something toxic. I rode with her for 20 minutes in the trailer because she would not have been able to stand. CBC showed no toxins. I told the clinic I thought it was trauma - maybe she had gotten kicked or stepped on where I saw her laying last. They told me it had to be something in her neck for it show up in the back legs. And it was fine. (Me thinking to myself - huh??, seriously....I disagree) She stayed the night on steroids. Long story short the clinic thought they had a perfect candidate for an EPM study. I did tell them to go ahead and do a spinal tap to rule it out as that was the kick they were on. We have gone around before with inside medicine although my outside vets are awesome. I kept telling them trauma - they kept saying no. They even refused to do back x-rays - I was wrong. She got better with the steroids. After our outside vet stepped in against politics we got the mare home with EPM meds - took 4 days. I consider them 4 wasted days of which she could have been treated at home. She no sooner got home and couldn't walk again. Her steroids had worn off. Gave her more and she could walk again. Outside vet requested a back x-ray - they did not find anything fortunately. EPM came back neg. She did DMSO by IV to get more inflammation out that the steroids weren't getting. I do use communicators, reiki, masterson, holistic medication, chiropractor, accupuncture, massage - my clinic does not believe in any of it. (I also do not like human medical doctors.) Many times one or the other has done more than the vet or doctor, not that I'd replace my vets but the others have their place. I do the basics of masterson and healing touch myself and started calling contacts. We also have a human physical therapist friend we talked to. We got her home and had the chiro look at her right away - she did accupunture on her, we did healing touch (energy work like reiki),massages, and used essential oils on her. We of course rearranged things so she would be with her sister who wouldn't hurt her. I noticed every time we worked on a very painful area her heart rate went way up from the pain then would go back done as we worked. I believe our vet even mentioned a murmur which ended up to be nothing. With in a few days a hoof print right on her spine showed up! It was just 2 vertabraes in front of he spinal tap area. Had they gone into the kick area I'm sure we'd have had more issues. Our physical therapist friend said every time the clinic pulled on her tail to help her walk or do another lameness test it made it worse. Accupunture was done again 2 weeks later. It took quite a few weeks of energy work, massages, and oils to get her feeling and moving good again. It took even longer to get the inflammation out of the spinal tap area then the actual kick area. Clinic told me she'd never jump again. They still insist that "we will never know what it was!" She went to 3 shows in 2013 and got her 20 points needed for her HOF. As of Aug 3rd she was retired. If her back had flared again she'd have been done then. She is still motoring around fine and happily retired. So... long but I wanted to share....hope your guy stays on track and it works out for you both too. It's so much better to have them retired and hanging around happy then the alternative. We were in the same stressful situation as you - give it more time or not? You can get very frustrated trying to find someone who's willing to help you find an answer. Fortunately I have learned to follow my heart as you did and it is very seldom wrong. In the end if we have to make that heart wrenching decision I believe it is the last thing we can do to for our beloved animals. Pam
