But it's certainly not all just in your head. Manipulating the spinal joints can help relieve pain and improve some range of movement, Ferreira says. Dr Aron Downie, a lecturer at Macquarie University's Department of Chiropractic, explains: "It provides movement into the spinal joints and this is thought to provide some pain relief … it provides a sense of muscle stretch as well. Downie says back pain is a very real problem: at any one time up to a third of people will find it limits their daily activities.
The key, he says, is to manage it in a holistic way to prevent it from persisting. Chiropractors, physiotherapists, osteopaths and some GPs are trained in spinal manipulative therapy and other overall pain management methods. Not everyone needs to see a therapist, Downie says, particularly if you only occasionally twist and pop your back without issue. But if you find you regularly have an urge to crack, there may be underlying problems to address.
A small proportion of chiropractors focus on joint popping alone, but Downie says this isn't following clinical guidelines for treating back pain. It's why he says if a chiropractor or other therapist isn't giving you strategies to look after yourself in a constructive way, find someone else. Ferreira agrees: "You need a treatment approach that will be more active than passive … If someone goes to a health professional and all they talk about is the massage they will give or the back cracking, that's a red flag.
Usually, joint cracking is harmless. There is no strong evidence it causes arthritis. Down the center of your back you'll find your spine, which you can think of as "the scaffolding for the entire body," according to Cedars-Sinai Spine Center. Your spine protects your spinal cord, a bundle of nerves that transmit messages between your brain and pretty much every part of your body. With the help of vertebrae, or interlocking bones, it also supports about half the weight in your body.
The average person is born with 33 vertebrae, but most adults only have 24 since some of the lower ones fuse together over time.
Your vertebrae are divided into sections: your cervical spine your neck bones , your thoracic spine the upper part of your back , your lumbar spine lower back , your sacrum which joins with your pelvis , and your coccyx tailbone. Your vertebrae connect with each other at the back via flexible joints, and rubbery cushions known as discs are in between each one to provide some cushioning. The most widely believed theory comes down to pockets of gas that hang out in your joints.
This isn't the same kind of gas that escapes from your body after you've had a ton of beans or protein bars This gas comes from a lubricant inside your joints known as synovial fluid , which helps give nutrients to the cartilage in your joints to help them glide smoothly.
When you apply force to your joints, pressure can build up and turn into dissolved gases like oxygen, nitrogen, and carbon dioxide. The thinking is that these gases shift—and emit a cracking noise as they dissipate—when you do an extreme stretch , Dr. Anand says. The gas actually shows up on X-rays and MRIs, and your surrounding tissues quickly reabsorb it after you crack your back, Lisa A. DeStefano, D. However, a buzzy study in PLOS One examined MRIs of knuckles cracking and argued that the cracking actually happens when a gas-filled cavity forms as the joints stretch, not when the gas bubbles themselves collapse.
