That cracking sound your joints make has probably left you curious — or maybe a little worried. In this episode, Dr. Thomas Etue of Kingfisher Chiropractic in Bellingham, Washington explains exactly what’s happening inside your joints when you hear that familiar pop.
Dr. Etue dives into the science behind joint cavitation and separates fact from fiction when it comes to common myths, like whether cracking your knuckles causes arthritis. He also walks listeners through what actually occurs during a chiropractic spinal adjustment and why it’s not as mysterious as it sounds.
Whether you’re a long-time chiropractic patient or just joint-curious, this episode gives you a clear, honest look at one of the most asked-about topics in the practice.
Hey there, and welcome back. I’m Doctor Thomas Etue, and you’re listening to the Kingfisher Chiropractic podcast, coming to you from right here in Bellingham, Washington. Today we’re talking about something I get asked about all the time — and I mean all the time. The cracking sound. Whether it’s your knuckles, your neck, your back… what is that sound? Is it bad for you? And what actually happens when a chiropractor adjusts your spine? Let’s dig into it.
So first — that sound. A lot of people hear a pop or a crack and they immediately think something broke, or something went wrong. I completely understand that reaction. But here’s the thing… that sound is actually pretty harmless in most cases. What you’re hearing is called cavitation. Inside your joints, there’s fluid — synovial fluid — that helps lubricate and cushion everything. When a joint is moved quickly through its range of motion, tiny gas bubbles form and release inside that fluid. And that release is what makes the popping sound. It’s not bones grinding. It’s not anything tearing. It’s just gas moving around in the joint space. Pretty fascinating when you think about it.
Now here’s what I hear a lot. People ask me, is it bad to crack your own knuckles? Will it give you arthritis? The good news is — the research really doesn’t support that idea. Cracking your knuckles on its own doesn’t appear to cause arthritis. That’s been looked at quite a bit over the years, and it’s largely considered a myth at this point. Now, if you’re forcefully twisting or yanking on your own joints repeatedly in ways they aren’t meant to move — that’s a different story. But the sound itself? Not the enemy.
Here’s what’s interesting, though — and this is where chiropractic adjustments are really different from just cracking yourself. When I perform a spinal adjustment, the goal isn’t to make noise. The goal is to restore proper movement to a joint that has become restricted or stuck. We call that a subluxation. And when a joint isn’t moving the way it should, it can affect the surrounding muscles, the nerves, and honestly — how your whole body feels and functions. The sound that sometimes happens during an adjustment is just a side effect of that joint releasing. Sometimes there’s a pop. Sometimes there isn’t. And both of those outcomes are completely normal.
So what can you do starting today? A few simple things. First, stay hydrated. Your joints need fluid to stay healthy, and water plays a big role in that. Second, keep moving. Joints that stay still for long periods tend to get stiff and restricted. Even just getting up and walking around every hour if you sit at a desk — that makes a real difference. And third, pay attention to how your body feels. Stiffness in the morning, aching in your neck or lower back, reduced range of motion — those are your body’s way of telling you something needs attention.
Now, when should you come in and see us? If you’re dealing with persistent stiffness or pain that isn’t going away on its own — that’s a good sign it’s time to get evaluated. If you feel like your range of motion has decreased, if you’re getting headaches regularly, or if you’ve had a recent injury… please don’t just wait it out hoping it resolves. A quick evaluation can tell us a lot, and we can put together a plan that actually makes sense for your body and your lifestyle.
I want you to feel empowered, not scared, when it comes to your spine and your joints. They’re incredibly resilient. And with the right care and attention, most people can feel significantly better than they do right now.
