A neurologist identifies the risks of sudden neck movements on blood vessels

 

Neurologist Alexander Tkachev points out that the habit of violently shaking the neck until a distinctive cracking sound is heard can damage the vertebral artery and, in rare cases, may cause an ischemic stroke.

According to him, the popping sound itself is not a sign of a serious condition. It often results from pressure changes within the synovial fluid, causing tiny gas bubbles to burst during movement. Sometimes, the popping sound is caused by tendons and ligaments.

The danger arises when a person deliberately tries to make a popping sound by moving their head quickly and sharply, because the vertebral arteries, which supply blood to the back of the brain, pass through the neck.

He says: "Excessive twisting or bending of the head can damage the lining of blood vessels—a condition called vertebral artery dissection. A blood clot may form at the site of injury, which can obstruct blood flow and, in some cases, may lead to an ischemic stroke."

The doctor notes that these complications are rare, and most people who crack their necks occasionally do not experience them. However, the risk increases in patients with vascular disease, congenital connective tissue weakness, neck injuries, or those who experience rough handling of the neck.

According to him, severe and unusual pain in the neck or back of the head after a sudden movement, dizziness, loss of balance, double vision, numbness in the extremities, or weakness warrant an urgent visit to the doctor.

He points out that the persistent urge to "stretch" the neck is often linked not to vertebral displacement, but to muscle strain, poor posture, a sedentary lifestyle, or spinal problems. The cracking sound may provide temporary relief, but it does not address the underlying cause of the pain.

To prevent problems, doctors recommend maintaining physical activity, practicing deep neck muscle exercises, properly organizing your workspace, and treating any underlying medical conditions. Occasional cracking sounds are not cause for concern, but sudden neck movements should not become a daily habit.
