Jointed stirrups and back pain.

I agree that you should seek medical assistance for your back pain. Back pain is not something you should ignore if it remains persistent. I have first hand experience as do many people with this issue and prompt attention is always best.

The kind of back pain that jointed stirrups are really going to help is if your back is hurting due to stiffness in your ankles or knees. If you're limping, or favoring, or doing anything else that is making a change in your body mechanics due to ankle or knee issues, that would make your back hurt. And jointed stirrups would help that. I have damage in both ankles, one knee, and a hip from prior athletic injuries, and jointed stirrups make a HUGE difference for me.

I don't think they would help back pain that doesn't come from a problem that starts in the legs, though.

What I *would* suggest, since you say it's come on with a change in your position and a lot more work, is a tube of arnica gel. Can't hurt to try it, and it would help sort out if this is muscular.

I'm 100% behind going to a chiro. I don't have insurance either but if I don't go, I end up near cripple and it effects my horse too.

My chiro is good. I have a session then it's back in 2 weeks, then back in 3 if I'm feeling good push it out to 4.
