Last week’s video mentioned this fast, so it’s worth slowing down on: if what’s actually irritated in your back is a facet joint instead of a disc, the exact same “safe” exercise can fix one and inflame the other. World Spine Day lands on October 16 this year, right in the middle of Bone and Joint Health Action Week, and the piece of that worth actually sitting with isn’t posture reminders. It’s this: you can’t pick the right movement until you know which structure you’re dealing with.
Coach’s Corner
I’ve had more than one client come in doing careful, disciplined extension work for a back they were sure had a bulging disc, because that’s what a friend’s physical therapist prescribed for a similar complaint. Turned out the actual source was a facet joint being compressed by the exact motion they were told to repeat daily. Nobody was lazy or wrong to try. They were just never told there are two very different structures back there that respond to opposite things.
The Two Most Common Sources of Mechanical Back Pain
There are a lot of causes for lower back pain. There are two structures that cause a lot of lower back pain. The disc, or the facet joint. The facet joints are the small, paired synovial joints at the back of each vertebra; they’re real joints, with cartilage and a joint capsule, not just connective tissue holding things together. Research places the facet joint as the primary source in the opposite movement pattern in an estimated 15–45% of chronic low back pain cases, which makes it far too common to keep lumping in with generic “disc pain.”
Why “Just Stretch It” Fails Half the Time
Here’s the part that actually changes what you should do about it: these two structures respond to opposite movements. Disc-related pain typically worsens with flexion (rounding forward) and often eases with extension, which is the entire logic behind the McKenzie press-up we broke down last week. Facet joint pain runs the other way. It worsens with extension and backward leaning, and tends to ease with flexion. So the same press-up that helps a disc-based presentation can directly load and irritate an inflamed facet joint. Same complaint on paper, same exercise handed out, opposite result, depending entirely on which structure is actually the problem.
What Bone and Joint Health Action Week Is Actually About
Bone and Joint Health Action Week (October 12–20) exists because most people, understandably, don’t think about their spine as a set of distinct structures until something hurts, and even then, the instinct is to treat “back pain” as one thing. It isn’t. The actual value of a week like this isn’t the awareness itself, it’s what the awareness is supposed to lead to: getting an actual read on which structure is involved before you commit to a movement pattern, instead of guessing based on what worked for someone else.
What This Means for How You Move
This is part of why ELDOA’s joint decompression approach is built the way it is. Rather than assuming one direction of movement is universally “safe” for the spine, the postures are structured to create space in a specific joint, which is useful regardless of whether the irritation started in a disc or a facet, because the goal isn’t forcing the spine into one prescribed direction. It’s relieving over compression at the actual level and joint that needs it.

Where to Start
Not knowing whether your pain is coming from a disc or a facet joint is the same kind of guessing that keeps people doing the wrong exercise, correctly, for months. Marja’s story is a real example of what happens on the other side of that: once her actual structure was identified instead of assumed, three fractured vertebrae and severe osteoporosis went from “you’ll never garden again” to gardening an hour and a half at a time. Read her full story to see what that specific-diagnosis approach actually looks like in practice.
