What Is Neck Pain (Cervicalgia) and Why Does It Happen?
Neck pain can make even the simplest parts of your day frustrating.
Turning your head while driving, sitting at your computer, sleeping comfortably, exercising, checking your blind spot, or looking down at your phone can suddenly become uncomfortable. For some people, neck pain is a temporary annoyance that improves within days. For others, it becomes a recurring problem that affects work, sleep, exercise, and quality of life.
One term commonly used by healthcare professionals to describe neck pain is cervicalgia.
But what exactly is cervicalgia? What causes it? And perhaps most importantly, when should you consider physical therapy?
In this first part of our series, we'll explore the basics of cervicalgia, common causes of neck pain, symptoms to watch for, and why getting the right diagnosis matters.
What Is Cervicalgia?
Cervicalgia simply means pain located in the cervical region of the spine — in other words, pain in the neck.
Your cervical spine consists of seven vertebrae that support your head and allow your neck to move in multiple directions. These bones, along with the discs, joints, muscles, ligaments, nerves, and surrounding tissues, work together to provide both mobility and stability. When one or more of these structures becomes irritated, overloaded, injured, or sensitive, you may experience neck pain. Cervicalgia isn't necessarily a diagnosis that tells you exactly what caused your pain. Rather, it describes the symptom. That's important because not all neck pain is the same.
Two people can both report "neck pain" while having completely different contributing factors. One person may have muscle-related pain after spending a weekend doing yard work. Another may develop neck pain after a motor vehicle accident. Someone else may have pain accompanied by symptoms traveling into the arm.
The appropriate treatment depends on the individual presentation.
What Does Neck Pain Feel Like?
Neck pain can take many forms. You might experience:
- A dull ache or soreness
- Sharp or stabbing pain
- Tightness or stiffness
- Muscle spasms
- Pain when turning or tilting your head
- Difficulty finding a comfortable sleeping position
- Pain between the neck and shoulder
- Headaches associated with neck discomfort
- Pain that increases after prolonged sitting
- Reduced neck mobility
- Pain that extends into the shoulder or upper back
Some people notice their symptoms primarily in the morning. Others find that pain increases toward the end of the workday. Your symptoms may also change depending on what you're doing.
For example, looking down at a phone for an extended period may aggravate symptoms, while walking or changing positions may make you feel better.
These patterns are valuable information for a physical therapist.
Common Causes of Cervicalgia
There isn't one universal cause of neck pain. Some common contributors include muscle strain, prolonged or repetitive positions, physical inactivity, injuries, age-related changes, and irritation of joints or nerves.
1. Muscle strain
Neck and upper-back muscles can become overloaded by activities they're not accustomed to.
This might happen after:
- Lifting something heavy
- Painting or doing home renovations
- Sleeping in an unfamiliar position
- Exercising differently than usual
- Working for long periods at a desk
- Repeatedly looking upward or downward
The resulting soreness can sometimes resolve naturally. When it doesn't, physical therapy can help identify why the problem is persisting.
2. Prolonged positions
Modern lifestyles can involve hours of sitting, driving, computer work, or looking at handheld devices. The issue isn't that there is one "perfect" posture that you must maintain all day. Instead, spending a long time in the same position can place continuous demands on certain tissues and reduce opportunities for movement.
A physical therapist can help you identify practical ways to vary your positions and build tolerance for the activities you need to perform.
3. Injury or trauma
Neck pain can occur after falls, sports injuries, collisions, or other traumatic events. Whiplash is one example. Symptoms can include neck pain, stiffness, headaches, and difficulty moving the neck. Following an injury, an appropriate evaluation is especially important because treatment should be based on the nature and severity of the injury.
4. Age-related changes
The structures of the cervical spine naturally change as we age. Discs can lose some of their height and elasticity, and joints may develop degenerative changes. Additionally, imaging findings don't always tell the entire story.
Many people have age-related changes on an X-ray or MRI without experiencing significant pain. Conversely, someone can experience considerable symptoms without having a dramatic imaging finding.
A good physical therapy evaluation considers the whole person — symptoms, movement, strength, function, medical history, and goals — rather than focusing exclusively on a picture.
5. Nerve irritation
Sometimes neck pain is accompanied by symptoms extending into the shoulder, arm, or hand.
This may occur when a nerve root in the cervical spine becomes irritated or compressed, a condition commonly referred to as cervical radiculopathy. Symptoms can include pain, numbness, tingling, weakness, or altered sensation in the arm or hand.
This presentation deserves a thorough evaluation because treatment may differ from treatment for uncomplicated muscular neck pain.
Why Does My Neck Hurt When I Work at a Computer?
If you work at a desk, you've probably heard that "bad posture" is responsible for neck pain. The reality is more nuanced. Your body is designed to move, adapt, and tolerate different positions. Sitting at a computer isn't automatically harmful. However, remaining in one position for long periods can contribute to discomfort, particularly when combined with inadequate movement, fatigue, stress, poor workstation setup, or insufficient strength and endurance. Physical therapy can help you look beyond simply "sitting up straight."
Your therapist may assess:
- Monitor height and positioning
- Keyboard and mouse setup
- Chair position
- Shoulder and upper-back movement
- Neck mobility
- Strength and endurance
- Work habits
- Frequency of movement breaks
- How your symptoms respond to different positions
The goal isn't necessarily to make you hold a rigid posture all day.
The goal is to help you develop a body and workspace that can comfortably handle the demands of your job.
When Should You Seek Help for Neck Pain?
Many episodes of uncomplicated neck pain improve over time. The American Physical Therapy Association notes that many people recover from an episode within approximately six to twelve weeks, although recovery varies considerably from person to person.
Consider scheduling an evaluation if:
- Your pain isn't improving
- Pain repeatedly returns
- Neck stiffness is limiting your activities
- You have difficulty sleeping because of your symptoms
- You can't comfortably turn your head
- Your symptoms are affecting work or exercise
- Pain extends into your shoulder or arm
- You notice numbness, tingling, or weakness
- You're changing your lifestyle because you're afraid of aggravating your neck
You don't necessarily have to wait until your pain becomes severe. Early assessment can help identify contributing factors and give you a plan for managing the problem.
How Physical Therapy Can Help
Physical therapy focuses on restoring movement and function rather than simply masking symptoms. During an evaluation, your physical therapist may assess your neck and upper-body movement, strength, flexibility, joint mobility, neurological function, posture, and functional limitations. Your treatment may include:
- Therapeutic exercise
- Mobility exercises
- Strengthening
- Manual therapy
- Education
- Ergonomic recommendations
- Activity modification
- Postural strategies
- A personalized home exercise program
- Gradual return to work, sports, and daily activities
The important word is personalized. The exercise that helps one person may not be appropriate for another. Your physical therapist should use your examination findings and response to movement to determine what is appropriate for you.
Frequently Asked Questions
Is cervicalgia the same thing as neck pain?
Yes. Cervicalgia is a medical term used to describe pain in the cervical region of the spine, or neck. It describes the location of the symptom rather than necessarily identifying its exact cause. Because neck pain can have many different causes, an evaluation can help determine the factors contributing to your particular symptoms.
How long does neck pain usually last?
Recovery varies depending on the cause, severity, and individual factors. Many episodes of neck pain improve within several weeks, but some problems persist or recur. If your pain isn't improving, is getting worse, or is interfering with your normal activities, consider having it evaluated by a physical therapist or other qualified healthcare professional.
Don't Let Neck Pain Become Your New Normal
Living with neck pain can gradually change how you move. You may stop exercising. You may avoid turning your head. You may reduce your work activity. You may start sleeping differently. Eventually, these adaptations can affect your strength, mobility, and confidence. You don't have to simply accept persistent neck pain as part of getting older or working at a desk.
A physical therapist can help determine what is contributing to your symptoms and create a plan designed around your goals.
