Pinched Nerve vs. Herniated Disc in the Neck: What's the Difference?

Your neck hurts, and now your arm tingles too. One friend says it's a pinched nerve. Another says it sounds like a slipped disc. Both may be partly right, because the two terms describe different parts of the same story.

What's the difference between a pinched nerve and a herniated disc?

A herniated disc is a cause. A pinched nerve is an effect. The disc problem describes what happened to the cushion. The pinched nerve describes what happened to the nerve.

Your neck has small, soft discs between its bones. Nerves branch off your spinal cord and leave through small openings beside those discs. A pinched nerve happens when one of these nerve roots is squeezed or irritated as it exits. That's the definition from the American Academy of Orthopaedic Surgeons (AAOS)¹. Doctors call it cervical radiculopathy. Our pinched nerve in the neck guide covers it in full.

A herniated disc is one thing that can do the squeezing. Bone spurs and narrowed openings from wear over time can do it too. And a disc can herniate without touching a nerve at all.

What is a herniated disc in the neck?

A herniated disc happens when part of the soft center of a disc pushes out through a tear in its tough outer layer. According to Mayo Clinic³, it's also called a slipped or ruptured disc. It's most common in the lower back, but it can happen in the neck too.

Most herniated discs come from age-related wear³. Discs get less flexible with time and can tear with an ordinary bend or twist. Lifting with your back, or twisting while lifting, can add to it. Often no single cause is found³.

What a herniated disc does depends on where it pushes. According to Mayo Clinic³, some people have no symptoms and only learn about the disc from imaging. When a neck disc presses on a nerve, the most pain is often in the shoulder and arm. Coughing or sneezing can make it worse.

The herniated disc guide covers discs in the neck and low back. If you've heard "bulging disc" too, see bulging disc vs. herniated disc.

What else can pinch a nerve in the neck?

Wear over time is the most common cause. According to Cleveland Clinic², age-related changes cause most pinched nerves in the neck. Discs lose height, and the body forms bone spurs. These changes can narrow the openings where nerves exit.

AAOS describes the same split by age¹. In older adults, worn discs and bone spurs are the usual cause. In younger adults, a herniated disc is more common, often after lifting, twisting, or bending.

Other conditions can also put pressure on nerves. Mayo Clinic lists rheumatoid arthritis and repeated overuse among them⁴. Learn more about wear-related changes in cervical spondylosis and about a bulging disc in the neck.

Can you tell them apart by how they feel?

Not reliably. When a herniated disc pinches a nerve, it causes the same arm symptoms as a bone spur pinching it. The nerve can't tell what's pressing on it.

A pinched nerve in the neck often causes more trouble in the arm than in the neck. According to Cleveland Clinic², symptoms include:

• Sharp or burning pain that travels into the shoulder, arm, or hand
• Tingling or pins and needles in the arm or fingers
• Numbness in part of the arm or hand
• Muscle weakness and weaker reflexes
• Pain that's worse when you tip your head back or strain your neck

Symptoms usually affect one side². Some people find relief by resting a hand on top of their head². Which fingers tingle can hint at which nerve is involved. The C7 nerve, which runs to the middle finger, is affected in over half of cases².

A herniated disc that doesn't touch a nerve may cause only neck pain, or nothing at all. So the feeling tells you a nerve is involved. It doesn't tell you what's pressing on it. Grip getting weaker? Read about arm weakness from a pinched nerve.

How do doctors tell which one you have?

It starts with a hands-on exam, not a scan. Your doctor asks when symptoms started and what makes them better or worse. Then they check strength, reflexes, and feeling in your arms and hands². They may ask you to move your neck and arm in ways that bring on or ease your symptoms².

X-rays show bone. According to Cleveland Clinic², they can show disc narrowing and narrowed openings where nerves exit. They can't show the disc itself or the nerve. At Chiropractic Company, X-rays are taken only when your exam calls for them.

When a closer look at a disc or nerve is needed, a medical doctor orders an MRI. According to AAOS¹, an MRI shows soft tissues such as herniated discs. A medical doctor may also order nerve tests to check how well a nerve is working^1,2. Your chiropractor will tell you if your exam points that way and help you get it.

When does neck and arm pain need emergency care?

Symptoms in both arms at once are also a reason to get checked right away. When any of these signs appear, a medical provider comes first.

Do they get better, and what helps?

Most do, without surgery. According to Cleveland Clinic², over 85% of pinched nerves in the neck clear up within 8 to 12 weeks without specific treatment. Some people feel better within days or weeks, and others take longer¹. Symptoms come back for up to a third of people².

AAOS says first care is usually nonsurgical¹. That often includes exercise and physical therapy. Care guidelines suggest guided exercise for nerve-related neck and arm pain⁶. They also say nerve symptoms that still limit you after three months need a physician's exam⁶.

At Chiropractic Company, your doctor looks for what's behind your symptoms, then talks through options. Care may include gentle joint movement, gentle muscle work, supervised strengthening, and desk and sleep tips. Research on spinal adjustments for a pinched nerve is limited. If you don't want your neck adjusted, say so, and your doctor won't. Try these gentle exercises for a pinched nerve in the neck as a starting point.

Physical therapy is available at our Menomonee Falls, Waukesha, and West Allis North clinics.
