A stiff neck is typically characterized by soreness and difficulty moving the neck, especially when trying to turn the head to the side. It may also be accompanied by a headache, neck pain, shoulder pain and/or arm pain. In order to look sideways or over the shoulder, an individual may need to turn the entire body instead of the stiff neck.

Most people are familiar with the pain and inconvenience of a stiff neck, whether it appeared upon waking up one morning or perhaps developed later in the day after some strenuous activity, such as moving furniture. In most cases, pain and stiffness go away naturally within a week. However, how an individual manages and cares for the stiff neck symptoms can affect pain levels, recovery time, and the likelihood of whether it will return.

Common Causes of Stiff Neck

By far the most common cause of a stiff neck is a muscle strain or soft tissue sprain. In particular, the levator scapulae muscle is susceptible to injury. Located at the back and side of the neck, the levator scapulae muscle connects the neck’s cervical spine with the shoulder. This muscle is controlled by the third and fourth cervical nerves (C3, C4).

The levator scapula muscle may be strained throughout the course of many common, everyday activities, such as:

The cause of the stiff neck may be obvious if symptoms start right away, such as after falling during a sporting event. If a stiff neck seems to develop out of nowhere, however, it could be difficult to pinpoint the exact cause.

Uncommon Causes of Stiff Neck

Sometimes neck stiffness is a reaction to an underlying disorder of the cervical spine, which helps support and move the neck in addition to protecting the spinal cord. Several examples of cervical spine disorders that can cause neck muscles to painfully spasm or tighten include:

This is not a complete list of conditions that can cause a stiff neck. While rare, several other possibilities exist, such as an infection or tumor.

Stiff Neck Symptoms

A stiff neck can vary in intensity, ranging anywhere from an annoying discomfort to extremely painful, sharp, and limiting. Typically, attempting to turn a stiff neck to a particular side or direction will eventually result in so much pain that the motion must be stopped.

See Neck Pain Symptoms

The amount of reduction in neck motion can affect the individual’s activity levels. For example, if the head cannot be significantly turned in one direction without excruciating pain, driving will likely need to be avoided until symptoms improve.1

Dos and Don’ts for a Stiff Neck

Oftentimes, taking it easy for a day or two is all that is needed to give the neck’s soft tissues a chance to heal. In cases where pain is significant, an individual may want to use an over-the-counter pain medication or apply ice and/or heat therapy.

See Medications for Back Pain and Neck Pain

Wearing a cervical collar to immobilize a stiff neck is not advised. Rather, an individual with a stiff neck should try to stick to normal activity levels if possible, especially after the first day or two.

When to See a Doctor for a Stiff Neck

If a stiff neck has not shown improvement after a week, it should be checked by a doctor. Also, regardless of how long it has lasted, a stiff neck accompanied by any red flag symptoms—such as a fever, headache, nausea or vomiting, or unexplained sleepiness—should be seen by a medical professional immediately.
