The Science of Cavitation
The pop you hear during a chiropractic adjustment — or when you move your neck and back — is called cavitation. Inside your joints, there's a layer of fluid that lubricates movement. When a joint is rapidly distracted (gently stretched), the pressure change causes dissolved gases in that fluid to briefly form a bubble and then release, creating the popping sound.
This is the same basic mechanism as cracking your knuckles — harmless, and not "bones cracking." It doesn't indicate anything is broken or damaged.
Is It Safe
When Popping Is Normal — and When It Isn't
Routine neck and back popping without pain or other symptoms is usually harmless — often just normal joint movement or self-manipulation habits. The pop in a professional chiropractic adjustment is a controlled, targeted version of the same phenomenon, performed after a thorough evaluation to ensure it's appropriate.
Where it becomes worth checking out is when popping is accompanied by pain, stiffness, restricted motion, or neurological symptoms like tingling or numbness.
Signs Worth Evaluating
If you notice any of the following alongside neck or back popping, an evaluation is a good idea:
- Popping accompanied by pain or sharp discomfort
- Persistent neck or back pain that doesn't ease
- Popping with numbness, tingling, or weakness
- Sounds that are grinding or grating rather than a clean pop
- New or changing symptoms after a car accident or injury
- Instability or a feeling the joint gives out

Common Questions
Popping & Adjustment FAQs
Is the popping in a chiropractic adjustment safe?
Yes — the pop (cavitation) is a normal, well-understood phenomenon that occurs when gas releases from a joint during movement. With a trained provider and proper evaluation beforehand, it's safe.
Can I crack my own neck or back?
Self-manipulation may provide brief relief but doesn't address why the joint is restricted. It can also become a habit that irritates surrounding tissue. A proper adjustment is targeted and controlled.
When should I see a chiropractor about popping?
When it comes with pain, limited motion, numbness, or follows an injury. See the checklist above for signs worth evaluating.
Why does my neck pop when I turn it?
Often it's normal cavitation — gas releasing from a joint. If it comes with pain, stiffness, or other symptoms, it's worth a quick evaluation to rule out anything structural.
Does the pop mean the adjustment worked?
Not necessarily — an adjustment can be effective without a pop, and a pop doesn't automatically mean alignment was restored. The outcome is what Dr. Hamel tracks.
