Chronic numbness: when should you see a chiropractor?

Jean-Marc is 52 years old. For the past eight months, he's had a tingling sensation in his right hand every morning - a slight tingling that passes after a few minutes' movement. So he does what most people do: he ignores it. He tells himself it's the sleeping position. It'll pass. It's no big deal.

Then one morning, the tingling continued all day. His right arm felt heavy. He starts dropping things without meaning to.

That day, he finally consulted.

Evaluation revealed compression of the C6 nerve root, caused by restricted mobility at C5-C6 aggravated by years of working posture. The signal had been there all along. The body was speaking. No one was listening - not even Jean-Marc.

If you too experience recurring numbness in your hands, arms or feet, your body may be sending the same kind of signal. The question isn't «Should I consult?». It's, «Why am I still waiting?»

Those ants that settle in - understanding the nerve signal 🧠

Numbness, tingling, pins and needles - what professionals call paresthesias - are not pains in themselves. They are communication signals.

Your nervous system manages billions of connections throughout your body. The nerves serving your arms, hands and feet originate in the spinal column. The cervical roots (C4 to C8) control the upper limbs. The lumbar roots (L4, L5, S1) control the lower limbs. When a vertebra loses its mobility, a disc compresses a nerve root, or a muscle contracts around a nerve structure, the signal becomes distorted.

What you feel as «pins and needles in your hand» is the physical translation of this disturbed message.

The problem with chronic paresthesia? You get used to it. You normalize what shouldn't be normal. And all the while, the underlying cause can progress silently.

Cervical radiculopathy - one of the most common causes of upper-limb numbness affects between 80 and 180 people out of 100,000 per year, with a peak around the age of 50. It's not a medical rarity: it's one of the conditions most frequently assessed and treated by chiropractors in Laval and on the North Shore.

Why numbness becomes chronic

Acute numbness happens to everyone. You sleep on your arm, you get up with pins and needles, it goes away in a few minutes - temporarily interrupted nerve traffic, nothing to worry about.

Chronic numbness is another story.

Chronic paresthesia occurs when symptoms persist or recur regularly for more than six weeks. At this stage, the body no longer compensates - it signals.

Several factors can transform a one-off problem into a persistent one:

Cumulative posture. Eight hours a day in front of a screen, shoulders slightly forward, neck slightly flexed. Week after week, the cervical vertebrae lose their natural mobility. The foramina - the openings where the nerve roots exit - gradually shrink. Not enough to trigger a sharp pain. Just enough to create that recurring tingling sensation.

Silent degeneration. An intervertebral disc can lose height for years without causing acute pain. At a certain threshold, the pressure becomes sufficient to irritate a nerve root. This is often when the numbness «appears» - when the process has been underway for a long time.

The tension-compression circle. An irritated nerve causes a protective muscle contraction. This contraction increases pressure on the nerve. Which increases irritation. Which increases the contraction. This circle, once set in motion, gradually closes over the months.

If you've ever experienced numbness in your hands at night, a situation we detail in our article on numb hands at night: causes and solutions, You may recognize this mechanism. When these symptoms spill over into the day, it's time to take the next step.

The 3 most common neuro-musculo-skeletal causes

Not all numbness is the same, and not all numbness has the same origin. Here are the three causes chiropractors evaluate first.

1. Cervical radiculopathy

The number-one cause. An irritated nerve root in the cervical vertebrae sends symptoms «down» the nerve path: shoulder, arm, forearm, hand, fingers. Paresthesia follows a precise path, depending on which root is affected. Numbness in the thumb and index finger often points to C6. Numbness in the middle and ring fingers often points to C7.

Compression can result from herniated cervical discs, osteoarthritis with foraminal stenosis, or restricted joint mobility - often in combination.

We have explored in detail what a numb arm - and its differential diagnosis - in a dedicated article. The key point to remember: when tingling follows a path from the neck to the hand, the cervical spine is almost always involved.

2. Carpal tunnel syndrome

The second most common cause, often confused with cervical radiculopathy. The median nerve, compressed as it passes through the wrist, creates classic numbness in the thumb, index and middle fingers - especially at night, and often relieved by shaking the hand. What sets this condition apart: symptoms generally do not extend beyond the wrist, and pain may radiate to the forearm in prolonged position.

A chiropractor can differentiate between these two clinical pictures during a comprehensive assessment. And both can coexist - what clinicians call double compression syndrome (double crush syndrome), where the nerve is irritated at both neck and wrist.

3. Lumbar radiculopathy

If you experience numbness in your feet or legs, the cause is almost always lumbar. A herniated disc at L4-L5 or L5-S1 compresses the sciatic or femoral nerve root. Tingling descends along a precise path in the leg or foot - clearly distinguishing it from numbness of circulatory or metabolic origin, which affects the whole foot more diffusely.

For all matters relating to spinal foot numbness, our article on numb feet and neurovertebral decompression details mechanisms and treatment options. And for sciatica pain in all its complexity, our sciatic nerve guide remains the benchmark.

Warning signs - when to go to the emergency room ⚠️

Let's be clear: not all numbness leads to a chiropractor's office. Some require urgent medical attention.

Call 911 or go immediately to the emergency room if your numbness is accompanied by :

• A chest pain or tightness in the chest
• A sudden numbness on one side of the face, or unexplained facial weakness
• A sudden loss of bladder or bowel control - surgical emergency (ponytail syndrome)
• A progressive and rapid muscle weakness in the arms or legs, especially if it has set in within a few hours
• A deterioration in general condition unexplained fever, rapid weight loss, severe fatigue

Such presentations are rare. But they do exist.

An experienced chiropractor recognizes these as early as the initial assessment, and immediately refers you to the right professional if necessary. This is a fundamental pillar of serious chiropractic practice: knowing how to direct the patient to the most appropriate resource.

For all progressive numbness without any of these warning signs - which represents the vast majority of cases - the chiropractor is often the first resource to consult for a complete neuro-musculo-skeletal evaluation.

What the chiropractor will assess during your first visit

Chiropractic assessment for chronic paresthesias is not a simple neck massage. It's a structured investigation that seeks to identify precisely which nerve structure is involved, and at what level.

It generally includes :

Assessment of joint mobility. The chiropractor palpates and mobilizes the vertebrae to identify segments that have lost their natural movement. A dysfunctional vertebra at C5-C6 that creates pressure on the C6 root - this level of precision guides the treatment.

Specific orthopedic tests. Spurling test (manual compression of the cervical spine to reproduce symptoms), Phalen and Tinel test (for carpal tunnel), leg-lift tests (for lumbar radiculopathy). These maneuvers reproduce or relieve symptoms in a diagnostic way.

Functional neurological assessment. Osteotendinous reflexes, skin sensitivity by dermatomes, muscle strength by myotomes. These data can be used to identify which nerve root is affected - not just «you have tingling in your hand», but «your left C6 root shows signs of compression».

Positional and occupational history. How many hours should I sit? What sleeping position? What physical activity routine? Chronic paresthesias almost always have a story - and that story holds the key to treatment.

Dr. Michèle Bernatchez, Chiropractor, DC, BSc, and Dr. François Poirier, Chiropractor, DC, BSc, at Clinique Chiro Ste-Rose for over 30 years, combine this rigorous clinical evaluation with technologies such as MRI when additional tests are needed to confirm a diagnosis.

Chiropractic treatment plan for persistent paresthesias

Once the source has been identified, chiropractic treatment for chronic numbness generally follows a multi-phase progression.

Restoring movement to the vertebrae. By restoring mobility to the dysfunctional segments, we reduce the mechanical pressure affecting the nerve root involved. The nerve signal, less compressed, begins to normalize. Paraesthesias gradually diminish - not all at once, but measurably over the course of several sessions.

Soft-tissue work. Muscles chronically contracted around a compressed area contribute to the problem. Targeted myofascial release techniques break the tension-compression cycle that sustains symptoms.

Neurovertebral decompression. For herniated discs with significant radicular compression, neurovertebral decompression creates negative pressure in the disc, promoting retraction of the herniated material. Clinique Chiro Ste-Rose offers this approach for appropriate cases of persistent radiculopathy, whether cervical or lumbar.

The personalized exercise program. No lasting chiropractic treatment works without appropriate strengthening. Exercises targeted to the problem area stabilize results and reduce the risk of long-term relapse.

Science supports this approach. A meta-analysis published in April 2025 in the Journal of Pain Research, A study of 8 randomized controlled trials involving 632 patients confirms that cervical manual therapy has a 68.1 % probability of being the optimal approach for improving disability related to cervical radiculopathy, compared with 2.8 % for exercises alone.

Chronic paresthesias don't disappear overnight. But with a structured, personalized plan, many patients begin to notice an improvement in the first few weeks - fewer nocturnal episodes, less heaviness in the arm, better sensitivity to touch.
