Then I'm not sure why you started talking about shoulders and yoga instead of walking...

Like, I agreed with you that yoga would help your shoulder.

It's just not the same as walking a mile 3/week for general chronic pain, which is why you had to change the injury and the treatment for an example of it working.

I'm legitimately not sure what the confusion here is.

Like, sometimes I take things as obvious when they're not to anyone, but you understand for walking to help stretch what is causing mobility issues, it has to have no other cause than lack of exercise?

And if they would have kept up the bare minimum of physical activity, they wouldn't have developed chronic pain?

For someone with chronic pain as a result of an actual health issue, you have to resolve the underlying issue.

But I legitimately can't think of how else to explain this, so if you don't clarify what you're having difficulty understanding here, I'm just not gonna be able to help.
