People may notice a slight popping or cracking sound when moving their neck. Often, the sound occurs due to the movement of air trapped within the fluid of the joints.

It may also occur due to slight changes in how the ligaments or tendons move. However, if swelling or pain accompanies it, the noises could indicate an underlying health condition.

There are several potential causes of neck noises. Some of them are benign, and others may require treatment.

Benign causes

A popping, cracking, or crunching sound in the neck or other joints is not necessarily a sign something is wrong. It is a common occurrence, even in younger people with no history of joint damage or injury.

Two common benign causes include air escaping from the synovial fluid that surrounds and lubricates the joints, and tight ligaments snapping off of one bone and onto another.

Typically, a person does not need to do anything to address the noises their neck makes during movement unless it causes pain or swelling.

Joint damage or injury

An injury can lead to degeneration and damage to the joints in the neck. Several things can cause neck injuries, such as car accidents, falls, or impact during sports.

When a person injures their neck, they may experience symptoms that include:

A person will likely know if they injured their neck in an accident. However, they should consider consulting a doctor for diagnosis and treatment if they have any doubts.


There are more than 100 different types of arthritis and related conditions that affect the joints, tissues around the joints, and other connective tissues. Several types of arthritis can affect the joints in the neck and spine, such as cervical spondylosis. This refers to a condition that causes deterioration of the vertebrae, discs, and ligaments in the neck or cervical spine.

In addition to pain and stiffness in the neck, arthritis can cause grinding or clicking noises when moving the neck.

Poor posture

Over time, poor posture can lead to wear and tear or damage to the neck. When this occurs, a person may experience pain in their neck, arms, head, or shoulders. Additionally, they may experience stiffness and clicking or popping noises when moving their neck.


Crepitus is the medical term for various sounds joints make when they move. This can include:

  • popping
  • grating
  • snapping
  • clicking
  • catching
  • clunking
  • grinding

Generally, these noises are due to air bubbles forming in the spaces between the joints. They are not typically a cause for concern. However, any joint noise that occurs for a prolonged period of time or that causes pain should be discussed with a healthcare professional.

To diagnose neck noises, a person will need to consult a healthcare professional. They will likely begin by reviewing a person’s medical history and performing a physical examination. This will include taking a person’s vital signs and reviewing symptoms. A healthcare professional will also assess range of motion and pain or discomfort when moving the neck.

In addition, they may request some tests to examine the structures in the neck or assess the function of these structures to help establish a diagnosis. These tests may include:

Treatment will depend on the underlying cause of symptoms. However, healthcare professionals will likely start with conservative treatments to help relieve symptoms. These can include:

  • performing physical therapy
  • wearing a cervical collar
  • taking prescription medications, such as muscle relaxants or pain relievers
  • taking over-the-counter (OTC) medications for pain and inflammation
  • receiving steroid injections
  • taking steps to correct posture when walking, standing, sitting, and sleeping

In some cases, a healthcare professional may recommend strength training exercises to help alleviate pain and stiffness. Strength training exercises can also help stretch the neck. Some examples include:

  • tilting the head from side to side by lowering the ear to the shoulder and back to a normal resting position, and repeating 5 times on each side
  • turning the head from side to side, looking over the shoulder, and repeating 5 times on each side
  • dropping the head forward so the chin reaches toward the chest and raising the head back up, and repeating 5 times

Some other strategies to alleviate neck popping and other symptoms can include:

A person may not need to contact a healthcare professional if they hear a popping or cracking sound with no other symptoms. In these cases, the popping likely occurs due to air escaping or tight ligaments snapping on the bones as they move.

If pain, stiffness, swelling, or other symptoms accompany the noises, a person should consider consulting a healthcare professional. They can examine and determine the cause and help provide treatment as necessary. A person should seek emergency care if they experience blunt force trauma resulting in injury, such as impact when playing a sport or during a car accident.

The following are answers to questions people frequently ask about crunching sounds in the neck.

How do you get rid of crunching sound in neck?

A crunching sound in the neck is often not something to be concerned about. However, if it is due to an underlying condition or injury, a doctor may recommend medication, physical therapy, or wearing a cervical collar to help manage symptoms. If it is due to poor posture, posture correcting techniques and devices may help.

What vitamins are good for bones and muscle health?

Vitamins and nutrients that are essential for bone and muscle health include vitamin D, calcium, and protein. Vitamin D helps the body to absorb calcium. Calcium promotes bone and teeth health. Protein is important for the maintenance of the muscles.

Should I be worried about neck crepitus?

Generally, neck crepitus is not cause for concern. However, if crunching, popping, or grating noises accompany pain or swelling, a person should consider speaking with a healthcare professional.

Hearing crunching noises from the neck during movement may not always require medical attention. These sounds can often occur due to air escaping the fluid surrounding the joints or from tight tendons rubbing or snapping against the bones. If the noise does not accompany other symptoms, a person likely does not need to do anything specifically to address the noise.

However, if pain, stiffness, or other symptoms occur, a person should consider contacting a doctor. They can help diagnose the cause and recommend treatments for any underlying condition. Treatment options often involve strength training, pain relievers, and posture correction.
