Kaswyn's situation

It's taken eight years, thousands of dollars, and many tears, but I've finally faced the facts and accepted this:  

Kaswyn is retired.

I've tried literally everything.  Nothing has worked.  Since I moved Kaswyn to this new barn he hasn't been sound.  I've tried more treatments that didn't work, and now I'm to the point where I just don't want him to hurt.  I'm afraid that he does though, and I want to figure out what I can do to make him more comfortable.  

I have him barefoot, getting trimmed every 4-5 weeks.  He's on Equithrive, a natural anti inflammatory, and he is back to being in standing wraps on his front legs when he's in his stall.  When the weather got warm his front legs swelled up a lot.  This made his left front neurectomy scar extremely painful.  The standing wraps take care of the swelling very well.  The guys who work at the barn are really super about getting the wraps on and off every day, so he may just need to stay in them from now on.  

I know that, regardless of all that I'm doing, Kaswyn isn't quite right.  Another rider at the barn noticed that he was resting his butt against his stall wall in an effort to take weight off of his back legs.  I suspect that the pain in his front leg from the swelling made him put too much weight behind and he has hock or stifle pain.  

Keep in mind that I've been riding him at the walk, for up to 15 minutes, occasionally trotting or cantering to check his soundness.  He has not been in any kind of full work.  After I walk him we do shoulder stretches to keep his shoulder from locking up.  That's been it.  

So he is retired, not even really in light work.  He's just walking only.  But I think he hurts so I might have the vet out and check his back legs.  Something tells me it's back end pain, as a result of front end pain.  I may change his supplement depending on what the vet has to say. 

Regardless, I'm not trying to "fix" him anymore.  I just want to reduce his pain and give him a good life.  Right now with a few hours a day on good grass and the rest of the day napping in his stall, then treats and hugs from me, that's a pretty good life.  I just need to manage his pain.  

I'll update when I call the vet.  I don't know why I haven't called yet. Just a wussy, I guess.  I don't want any bad news.
