Popping joints are common. Some researchers used to think the popping sound was an air bubble between collapsing bones, while others believed the sound came from the recoil of muscle ligaments.
Doctors call popping joints crepitus. Many people dislike the sound of popping or cracking joints, even though healthy joints can make noises. One 2017 study showed that popping joints made people experience negative thoughts, emotions, and even avoid healthful activities.

More research into the exact process behind popping joints is still necessary, however.
Understanding joint popping
To date, there is no evidence to suggest that popping a person’s own joints has negative effects, only a slight increase in
When talking about popping joints, professionals differentiate between a person physically popping their own joints and condition-related popping.
If there is pain, swelling, limited range of motion, or a history of injury, the popping could have some links to a more serious health condition.
Popping with a link to a health condition generally occurs
Physical popping has no pain and is not a cause for concern.
Some conditions cause popping joints to happen more frequently, such as in some forms of arthritis.
As arthritis progresses, popping can become more frequent.
Osteoarthritis (OA) causes the cartilage in a joint to become thinner and more ragged. This thinning and wear can cause pain as joints rub against each other, and it also has links to popping joints. Popping joints occur more frequently as OA progresses.
People should always treat self-reported findings with caution.
As mentioned above, other studies show that people dislike joint popping and associate it with unhealthy joints, and so this feeling may influence self-reported findings.
Popping joints can also occur with forms of inflammatory arthritis, such as rheumatoid arthritis.
High-pitched popping sounds from joints are more likely to be from inflammatory arthritis. Lower sounds can be from either inflammatory or noninflammatory arthritis, although this may be hard to distinguish.
Inflammation around tendons
Although not a popping joint, inflammation surrounding tendons can also cause crunching, cracking, or popping sounds.
Injury or inflammation to the tendon or the areas around tendons, such as tendinitis or tennis elbow, bursitis, or tenosynovitis, are sometimes accompanied by popping sounds.

During a chiropractic adjustment, the practitioner uses pressure to help realign joints that may be somewhat out of alignment but not dislocated.
This realignment may or may not involve a popping noise. There is no evidence that a popping joint
Typically, popping joints are not a cause for concern.
It is important to differentiate between joint noise with pain and swelling and joint noise without pain. Joint noise without pain is very normal, common in healthy joints, and generally not a cause for concern.
People should see a doctor if they are experiencing popping joints with pain.
