C6-C7: What Symptoms at This Neck Level Mean

By Yama Zafer, D.C.

C6-C7 is the joint between the sixth and seventh cervical vertebrae, the lowest freely moving level of the neck. It is also one of the two levels most commonly involved. The C7 nerve root leaving here has a recognizable territory: the back of the arm, the triceps muscle and the middle finger.

Weakness at this level shows as difficulty straightening the elbow against resistance or pushing a door closed, and the triceps reflex may be reduced. Resting the affected arm on top of the head often lessens the symptoms, which can point to a nerve-related cause rather than the shoulder.

At CSC, care for C6-C7 is non-rotatory and gentle, with physiotherapy alongside, and it is kept within what you can comfortably tolerate. The sections below cover where the level sits, which nerves it affects, C7 nerve damage symptoms, the disc and the spinal cord. Then come the 999 warning signs, the neck as one chain and the plan of care.

Key Takeaways About the C6-C7 Level

QuestionShort answer
Where is C6-C7?At the base of the neck, where the flexible cervical spine meets the stiffer upper back. The bump felt there is usually the C7 spinous process, called the vertebra prominens (Kaiser and colleagues, 2023).
Which nerves does C6-C7 affect?Mainly the C7 nerve root, which exits here and serves the triceps, the wrist and finger extensors, and the skin around the middle finger. The C6 root leaves one level higher, at C5-C6.
What does C7 nerve damage feel like?Pain spreading down the back of the arm, tingling or numbness toward the middle finger, and weakness straightening the elbow. The triceps reflex may be reduced, and grip can feel weaker too.
Does a disc bulge at C6-C7 press on the nerve?Not in my view, not as a true bulge in the shape an MRI shows. When the arm hurts alongside a reported bulge, the disc is in transition and pushes further out with sitting and standing.
How often is C6-C7 involved?Often. The C7 root accounts for more than half of nerve root cases in the neck (Margetis and colleagues, 2025). Disc herniations are reported most often at C5-C6 and C6-C7.
Does a scan finding at C6-C7 always matter?No. Disc and joint changes are common in people with no symptoms, so a scan finding at C6-C7 matters only when it matches the examination. That is why the exam comes first.
Which signs point to the spinal cord?Clumsy hands, an unsteady walk or new urgency to pass urine, sometimes with little neck pain (Margetis and colleagues, 2025). These need prompt medical assessment, and a change in bladder or bowel control needs it the same day.
Is yoga safe with a C6-C7 disc problem?No. With a disc problem at C6-C7, yoga must be avoided, and it is never part of the plan. My rule for a damaged disc in the Back Pain to Leg Pain talk: “No twisting, no repetitive movements.”
What does care at CSC involve?Assessment first, then non-rotatory chiropractic care, registered physiotherapy and exercise, kept within what you can comfortably tolerate. Surgery and injections come last, only if focused conservative care, built on the imaging and examination findings, has not worked.

Where C6-C7 Sits and What the C7 Nerve Supplies

The C6-C7 level includes the intervertebral disc between the two vertebrae and the two small facet joints behind it. It is the last freely moving level before the thoracic spine. So it carries a large share of the load when you look down, lift or hold the head forward for long periods.

Compared with the levels above it, C6-C7 moves less, and as I see it that makes it harder to injure. Injury still happens here, though: C6-C7 is a common site of it, often after the neck has carried too much load.

C7 is a transitional bone. Its long, single spinous process, the vertebra prominens, can be felt at the base of the neck. Its body and lower joints are closer to those of the upper back (Kaiser and colleagues, 2023).

The vertebral arteries usually pass in front of C7 and enter the side openings of C6 instead (Kaiser and colleagues, 2023).

The C7 nerve root leaves the spine through an opening at this level. When it is irritated, typical signs include pain spreading down the back of the arm and tingling or numbness toward the middle finger. Weakness when straightening the elbow and a reduced triceps reflex are typical too.

Grip can feel weaker as well, although grip strength depends on several nerve roots, not C7 alone. Related pages explain a pinched nerve and nerve pain in more detail.

The neighboring levels behave differently. See the guides to C2-C3, C3-C4, C4-C5, C5-C6 and C7-T1, and the degenerative disc disease page for disc changes that come with age.

Which Nerves C6 and C7 Affect

The C7 root leaves the spine at C6-C7, and the C6 root one level up, at C5-C6. So a problem at C6-C7 mainly affects C7, while a C5-C6 problem mainly affects C6.

Between them, the two roots serve much of the arm. The C6 root runs toward the thumb and index finger. The C7 root runs down the back of the arm toward the middle finger.

Strength testing checks C6 through the wrist extensors and C7 through the triceps. Reflexes are tested at the biceps for C5 and C6, at the brachioradialis for C6 and at the triceps for C7 (Margetis and colleagues, 2025).

Below them, the C8 root leaves at C7-T1 and serves the finger flexors. T1 serves the small muscles of the hand (Margetis and colleagues, 2025). The C7-T1 guide covers that level.

Symptoms When the Nerve Root Is Damaged

Nerve damage at C6-C7 usually means an irritated or compressed C7 root. Symptoms tend to sit on one side. They often worsen when the neck bends back or turns toward that side, or with overhead arm work (Margetis and colleagues, 2025).

The usual signs are:

  • Pain down the back of the arm, sometimes into the forearm.
  • Tingling or numbness toward the middle finger.
  • Weakness straightening the elbow or pushing a door closed.
  • A reduced triceps reflex.
  • A weaker grip, although grip depends on several nerve roots.
  • Neck pain and stiffness alongside the arm symptoms.

In my experience, the pain can start where the neck meets the shoulders. It can spread over the top of the shoulder blade, down to its lower edge and into the space between the shoulder blades.

From there it can travel down the arm toward the hand. The middle finger is often involved, and at times the index or ring finger as well. The pain can be sharp or dull, with numbness and tingling in the fingers.

The C7 root also works muscles. Weakness straightening the elbow, bending the wrist or straightening the fingers points to this level.

Similar symptoms can come from the shoulder or from a nerve trapped lower in the arm, as in carpal tunnel syndrome. That is why the examination matters more than the label.

The long-term outlook is usually good. The Rochester study followed 561 people for a median of 4.9 years. By the last follow-up, 90% had no symptoms or were only mildly limited (Radhakrishnan and colleagues, 1994).

The condition came back in about a third of them, 31.7%, which is one reason posture and work habits are part of the plan.

Weakness that keeps getting worse needs a prompt assessment. Where weakness is present, conservative care can continue only while the weakness itself is improving.

Fracture After a Fall or Crash

A fracture of C6 or C7 usually follows a fall, a crash or a heavy blow. Severe pain at the base of the neck after such an injury is an emergency. So are numbness, weakness or lost control of the arms or legs.

Call 999, keep the person lying still, and leave the head and neck exactly as they are. The signs of a possible spinal injury are listed under the 999 heading below.

Disc Bulge and Herniation at This Level

A bulge reported on an MRI does not, in my view, press on the C7 root in the shape the scan shows. The scan is taken lying down, when the disc carries no body weight.

Upright, after hours of sitting or driving, a weakened disc pushes further out. I call that a disc in transition: it then acts like a protrusion, a prolapse or a herniation, and that can explain arm symptoms.

In Why Spinal Discs Get Damaged, my words are: “As the fibers of the annulus weaken, the nucleus continuously protrudes outwards.” It moves “towards sensitive neuronal tissues, be it the spinal cord or spinal nerves, and this is a progressive condition.”

Why Spinal Discs Get Damaged

The stages continue past herniation. The disc can extrude, and a piece can tear partly away, a fragmented disc. Once that piece comes away entirely, the disc is called fully fragmented, or sequestered.

When a C6-C7 disc does cause symptoms, they usually follow the C7 root: the back of the arm, the middle finger and the triceps. Neck pain and stiffness are common alongside them.

Care for a C6-C7 disc stays gentle and non-rotatory, never twisting or cracking, and yoga is ruled out. The disc bulge guide explains the condition across the spine.

Spinal Cord Compression at C6-C7

The spinal cord passes through C6-C7 on its way to the arms and legs. Pressure on it is called myelopathy. It shows differently from a pinched nerve: in both hands, in the walk or in the bladder rather than along one arm.

Hand clumsiness, an unsteady walk or urgency to pass urine can appear even without much neck pain. These signs call for prompt evaluation (Margetis and colleagues, 2025).

Cord compression turned up in 5.3% of 1,211 people scanned without symptoms. C6-C7 held 27% of those cases, second only to C5-C6 at 41% (Nakashima and colleagues, 2015).

Call 999 for These Signs

A stroke sign that appears suddenly is not a reason to book an appointment. Call 999 at once, and do not drive yourself, for any sign on the stroke list of the US Centers for Disease Control and Prevention:

  • Face, arm or leg weakness or numbness that begins all at once, mainly on one side of the body.
  • Confusion that starts suddenly, or speech that is slurred, hard to produce or hard to follow.
  • Vision that suddenly fails or blurs in one eye or in both.
  • A sudden loss of balance, dizziness, poor coordination or trouble walking.
  • A sudden, very severe headache for which there is no known cause.

After a crash, a fall or a blow, Mayo Clinic's first-aid page names the signs below as reasons to suspect a spinal injury. A broken C7 is one such injury. Call 999, keep the person still and keep the head and neck from moving:

  • Strong force struck the head or the back.
  • Severe neck or back pain follows the injury.
  • A head injury brings an ongoing change in alertness or consciousness.
  • Numbness, weakness or paralysis appears, or control of the limbs, bladder or bowels is lost.
  • The neck or body is twisted or sits in an odd position.

Assessment for Neck and Arm Symptoms at Two KL Centers

If you have neck pain with arm symptoms, or a scan report that mentions C6-C7, a first visit begins with your story and history. Then come checks of movement, strength, sensation and reflexes, and any imaging you bring is read alongside those findings.

For directions and opening hours, see the Bukit Damansara contact page or the Bandar Sri Damansara contact page. You can also call or message either center:

Common Problems at C6-C7

Disc herniation, wear in the discs and joints, and narrowing of the nerve openings are all seen at this level:

  • Disc bulge and herniation: a disc bulge is a broad extension of the disc beyond its normal margin. A herniated disc is a more localized displacement that may press on the C7 nerve root.
  • Cervical spondylosis: changes in the discs and joints that come with age, including bone spurs. See the cervical spondylosis guide.
  • Facet joint changes: thickening of the facet joints, the small paired joints behind the vertebrae, described on the facet hypertrophy page.
  • Narrowing of the canal or nerve openings: covered on the spinal stenosis page. Narrowing of the central canal can affect the spinal cord, which changes how the problem is managed.
  • Slippage: forward or backward slippage of one vertebra on another is less common in the lower neck; see spondylolisthesis.
  • Injury: a collision or fall can strain the discs, ligaments and joints at this level. The whiplash guide covers this.

How Often Is C6-C7 Involved?

In a population-based study of cervical radiculopathy in Rochester, Minnesota, the C7 nerve root was the root most often affected, followed by C6. Among disc herniations in the neck, C5-C6 and C6-C7 are the levels most often reported.

That study counted 561 people over 15 years, and new cases peaked at ages 50 to 54. Only 14.8% could link the start to exertion or an injury (Radhakrishnan and colleagues, 1994).

A recent review puts C7 at more than half of all nerve root cases in the neck (Margetis and colleagues, 2025). These figures describe groups of people; they do not predict what any one person's neck is doing.

What Imaging Can and Cannot Tell You

MRI studies of people with no neck symptoms have found disc bulges, disc degeneration and narrowing in a substantial share of them. The proportion rises with age.

In one such study of 63 volunteers, a disc was degenerated or narrowed in 25% of those under 40. Over 40, the figure was almost 60% (Boden and colleagues, 1990).

That is why a report mentioning C6-C7 is only one piece of information. It matters when it matches your symptoms and examination findings, and it may be incidental when it does not.

How Problems at This Level Are Assessed

Assessment looks at the whole neck, not one level in isolation. It includes your history, neck and upper back movement, and shoulder movement to rule the shoulder in or out.

Strength in the arm and hand, sensation, reflexes, and whether certain positions settle or reproduce arm symptoms are also examined. The upper neck is checked too, because stiffness in one part of the neck can change the load on another; see the upper neck guide.

The Base of a Connected Neck

The neck works as one kinematic chain, in my view, and C6-C7 is its lowest moving link. What happens here travels upward through the middle levels to the top of the neck and the skull base. In the end, it reaches the brainstem and the brain.

I call it a domino effect. A head held forward at a laptop, a phone or a handheld device loads the lower neck heavily. In my view, the lower levels bear that stress at least as much as the upper ones.

Next to the top joints, the neck's workhorses are C4-C5 and C5-C6, and C6-C7 sits directly beneath them, taking its share of the same load.

As I see it, a C6-C7 problem seldom stands alone. Its disc and joints often get damaged when C4-C5, C5-C6 or both already have problems.

I often see it in people with long-standing neck problems, and after car accidents, whiplash and sports injuries.

The multifidus and the erector spinae link every level from the skull base down to C7. As I see it, they load each segment in turn and, over time, together bring degenerative and spondylotic change.

If the strain keeps building, the cord or a spinal nerve may become impinged, and at times the cord develops edema or degenerative change.

The C2-C3 guide and the upper cervical guide explain the four small suboccipital muscles and the myodural bridges at the top of the neck.

Conservative Care for C6-C7 at CSC

Care at CSC follows a conservative sequence: assessment first, then non-rotatory chiropractic care, registered physiotherapy and guided exercise. Depending on the findings, a plan may include:

Yoga is not part of any C6-C7 plan: with a disc problem at this level, it must be avoided.

Physiotherapy and chiropractic belong in the same plan. When people ask me to pick one, my answer in Is Chiropractic Safe? 13 Questions Answered is “Don't choose between one or the other. Choose both.”

Care is kept within what you can comfortably tolerate. If a method hurts, tell me straight away and I make it lighter. My motto stays the same: “No pain, more gain.”

Progress is measured against specific things a person has difficulty doing, and the plan is reviewed if there is no measurable change. My rule, set out in Is Chiropractic Safe? 13 Questions Answered, is simple. No change by the fifth session means the plan is reconsidered, and at the tenth we choose the next step together.

Medical review, imaging or referral is discussed openly when it may be appropriate. Injections or surgery come into the picture only if focused conservative care, given properly, has not worked.

Surgery is the end of the road for me, never the starting point. In Sciatica vs Slipped Disc: Video Explanation, I say: “Surgery should be the last option. Exhaust conservative route.”

The possible effects and risks are explained before care begins. The fee for a plan is explained and agreed before care begins.

No Twisting or Cracking at This Level

Radiating arm pain, numbness, tingling, or neck pain spreading between the shoulder blades or down the chest rules out rotatory maneuvers and exercises.

That holds whether the problem is recent or old, and with or without weakness or numbness. Nobody should crack or twist such a neck: not a chiropractor, a physiotherapist, a medical doctor or an orthopedic surgeon.

Chest pain should be checked by a doctor first, as it can come from the heart.

Wrong exercises are common too. With a C6-C7 problem, I would not follow most of the exercise advice in online videos. Some of it is sound and a lot of it is not.

Even good advice has to fit the person. Each exercise has to be tailored to that person's presentation, even when it targets the right level.

My View on Injections, Nucleoplasty and C6-C7 Surgery

This is my personal opinion. The neck is one of the body's most mobile joints: we nod, turn and look all day, so it can never truly be immobilized.

Neck surgery often has to be repeated, and in my experience it never ends the problem. I believe it belongs only after a targeted, focused course of conservative care has been exhausted.

Not any conservative care will do. Many therapies on offer are of no use for C6-C7, and a lot of them harm people with a problem at this level. Care has to fit the underlying condition closely. By that I mean care planned from the imaging and examination findings, aimed at what they document, never run-of-the-mill neck treatment.

Injections are not something I recommend, and neither is nucleoplasty, which I consider of no value. Hundreds of my patients over the years, perhaps more, had no improvement at all after it, and many were worse.

If an invasive step is needed at all, I advise against radiofrequency nucleoplasty, whether into the disc or into the facet joints. I advise against facet joint injections of any kind as well.

Research supports parts of this view. A 2025 Cochrane review found too little evidence to back nucleoplasty for arm pain caused by a herniated neck disc (de Rooij and colleagues, 2025). Each of its four trials carried a high risk of bias.

In a double-blind lower back trial, radiofrequency heating of the disc wall did no better than a sham (Kvarstein and colleagues, 2009). The trial's authors did not recommend it.

Steroid injections carry risks of their own. A 2019 Radiology report looked at steroid injections given into hip and knee joints (Kompel and colleagues, 2019).

After those injections, it described arthritis that worsened faster, fractures beneath the cartilage, complications of bone death and rapid joint destruction. These were hip and knee findings, not neck findings.

After a front-of-neck fusion, the next level developed new nerve or cord problems at about 2.9% a year (Hilibrand and colleagues, 1999). Over ten years, about a quarter of patients, 25.6%, were expected to have them.

Why CSC Does Not Use Y-Strap or Ring Dinger Neck Pulls

Techniques such as Y-Strap or Ring Dinger® pulls apply a sudden, strong pull through the neck. CSC does not use them, as a precaution: gentler options exist for the lower neck.

A quick pull loads the discs and ligaments at levels such as C6-C7 without a detailed assessment first. The neck-pull risks article explains this further.

In Neck Cracks Are Dangerous, my rule is plain: “Aggressive neck care is never good and should always be avoided.”

Neck Cracks Are Dangerous

Its chapters and an edited transcript sit on the Neck Cracks Are Dangerous video page.

When to See a Doctor First

A change in bladder or bowel control needs medical attention the same day.

Arm or hand weakness that keeps getting worse, clumsy hands, or a change in walking or balance needs prompt assessment by a competent provider. Depending on what that assessment shows, focused conservative care may still be a reasonable route.

Neck pain with fever, unexplained weight loss, or after a serious fall or accident should be checked by a doctor first. Night sweats, a weak immune system, constant pain at rest and a tender spine are further red flags (Margetis and colleagues, 2025). They can point to infection or a tumor and need prompt assessment.

Frequently Asked Questions About C6-C7

What does the C6-C7 level do?

It allows movement at the base of the neck, transfers load between the neck and upper back, and protects the C7 nerve root. That root serves the triceps, the wrist and finger extensors and sensation around the middle finger. Because it is the last freely moving level above the upper back, it carries much of the load when the head is held forward.

What symptoms can come from C6-C7?

Neck pain and stiffness, pain down the back of the arm, tingling toward the middle finger, and weakness when straightening the elbow. Similar symptoms can come from the shoulder or a nerve in the arm, which is why an examination matters. Signs in both hands, an unsteady walk or a change in bladder control point to the spinal cord and need prompt medical assessment.

Does a C6-C7 disc finding on MRI mean I need surgery?

Not by itself. Many people with disc findings at C6-C7 manage with focused conservative care. Surgery is usually discussed when there are signs of spinal cord involvement or when weakness keeps getting worse. It is also discussed when focused care, planned from the imaging and the examination, has brought no change. In my view, surgery comes last, once care of that kind has been done properly and has not worked.

What nerves are affected by C6 and C7?

A C6-C7 problem mainly affects the C7 nerve root, which exits at this level. It runs to the triceps, the back of the arm and the middle finger. The C6 root exits one level higher, at C5-C6, and serves the thumb side of the hand and the wrist extensors. Strength testing and the triceps, biceps and brachioradialis reflexes show which root is involved.

What are the symptoms of C6-C7 nerve damage?

Pain down the back of the arm, tingling or numbness toward the middle finger, weakness straightening the elbow and a reduced triceps reflex. Symptoms usually affect one side and can worsen when the neck bends back or turns toward that side. In a long-term study, 90% of people with a pinched neck nerve had no symptoms or only mild limits at the last follow-up.

Which bone sticks out at the neck's base?

C7 is the lowest neck bone, at the base of the neck where it meets the upper back. Its long single spinous process, the vertebra prominens, is usually the bump most people can feel there. C7 is a transitional bone: its body and lower joints look more like those of the upper back than those of the neck.

What are the symptoms of a C7 fracture?

A broken C7 usually follows a fall, a crash or a heavy blow. Severe pain at the base of the neck after such an injury is an emergency. So are numbness, weakness or lost control of the arms or legs, and a neck held in an odd position. Call 999 at once and stop the person from moving their head or neck.

Is pressure on the spinal cord here serious?

It can be. In people scanned without symptoms, C6-C7 was the second most common level for cord compression, after C5-C6. When the cord is pressed, signs show in both hands, in the walk or in bladder control rather than along one nerve. These need prompt medical assessment, and a change in bladder or bowel control needs it the same day.

Which activities should I avoid with this disc problem?

Yoga must be avoided, as must forceful pulling devices such as the Y-Strap and the Ring Dinger. For a damaged disc, my rule is no twisting and no repetitive movements. Hours spent looking down at a laptop or phone strain the base of the neck. Short breaks to move the neck every half hour are worth building into the day.
