Please tell me all your success stories and best practice management. 

Personally I would go to your vet for these answers. 

Well, of course I've been to the vet. I am doing what he recommended. I would like, as stated, success stories. I need to hear from people who have experience with this disease. I'm sure there are many different experiences that I can learn from. 

I have one that was diagnosed navicular about 10 years ago now. I ran him for 5 more years, bu he got hurt and retired since he was 20 at that point. Still ride him several days a week now at 25. We raised his heels and the toe of his shoe is rolled for better breakover. When I was still running him I injected his coffins twice a year, seemed to help. I kept him off hard ground riding, so I had to make sure places had a softer spot to warm up if there wasn't an actual warm up arena. He has progressed slightly over the years, but we just slightly adjst his hoof angle a little bit and he goes back to normal. I don't have him injected anymore as he just rides at home to stay moving. I do also have PHT bells I used when he was running, I like those. I never had to pad, but that's another option you could try. A lot of barrel horses are navicular and do just fine for quite some time, just depends how fast it progresses. We have another one we've done the OSPHOS on with really good results 

Look Up Freedom shoes. They are kind of an aluminum plate. You will see instant results. It allows the horse to move how they need to for the best relief. I have used them on several horses!

Flitastic are you still running barrels in the Freedom shoes? I'm 3 weeks into a set on my good horse but haven't made a run yet. 

If you go the route of nerving a navicular horse make sure you have them on a small lot, pick hooves am and pm. They can fully have an abcess and you could have no idea if they are nerved. We had a horse boarded at our house that was nerved and they missed picking hooves... an abcess looked healed and turns out it was festering up his leg. He NEVER took an off step. Hopefully you can manage one without having to nerve one. Even thhough this one wasnt my horse it is burned in my memory. 

Also curious if you are running in these.
