A patient came into my office a few months ago convinced she had carpal tunnel syndrome. She'd Googled her symptoms — numbness and tingling in her hand that woke her up at night, some weakness when gripping, discomfort that crept up her forearm by the end of the workday. Carpal tunnel was the first result every time. She'd already bought a wrist brace. She was wondering whether surgery was in her future.
After a thorough assessment, I told her what I tell a lot of patients: yes, there's nerve involvement here. But it's not coming from your wrist. It's coming from your neck.
The brace wasn't going to fix that. And neither was wrist surgery.
Get To The Root
Carpal tunnel syndrome is one of the most Googled musculoskeletal conditions there is — and one of the most misunderstood. The symptoms (numbness, tingling, weakness in the hand) are real and sometimes debilitating. But those symptoms can be produced by multiple different structures along the nerve's path from your cervical spine all the way down to your fingertips. Assuming the problem is at the wrist is where many people — and unfortunately, some practitioners — start to go wrong.
My job as a chiropractor is to figure out where the problem actually is before we start treating it. That requires a differential diagnosis: a systematic process of ruling out other causes before landing on a conclusion.
What Carpal Tunnel Syndrome Actually Is
Let's start with the real thing. Carpal tunnel syndrome (CTS) is a compression of the median nerve as it passes through the carpal tunnel — a narrow passageway on the palmar side of your wrist, formed by the carpal bones and the transverse carpal ligament.
When the tunnel becomes narrowed or the tissues inside become inflamed (from repetitive use, fluid retention, systemic conditions like hypothyroidism or diabetes, or prolonged wrist positioning), the median nerve gets squeezed. The result is predictable: numbness and tingling in the thumb, index, middle, and half of the ring finger (the median nerve's territory), weakness in pinch grip, and discomfort that tends to be worse at night or with sustained wrist flexion.
CTS is genuinely common — it affects 3–6% of women and 0.6–2% of men, with peak onset between ages 40 and 60. Desk workers, new parents (postpartum is a major risk factor), tradespeople with vibrating tools, and people with metabolic conditions are all higher-risk groups.
But here's what that prevalence also means: it's such a well-known diagnosis that it gets applied reflexively to anyone with hand tingling — even when the source is somewhere else entirely.
What I'm Ruling Out First
When a patient presents with hand numbness and tingling, here is what I'm thinking about before I confirm CTS:
Cervical Radiculopathy (C6 or C7)
This is the most common mimic I see in clinical practice. The C6 and C7 nerve roots — which exit your cervical spine (neck) — supply sensation and motor function to nearly the same territory as the median nerve. A disc herniation, arthritic spur, or joint dysfunction at the C5/6 or C6/7 level can produce hand tingling that is almost indistinguishable from CTS based on symptoms alone.
The distinction matters enormously. The Spurling's test (compressing the cervical spine with the head tilted toward the symptomatic side) will often reproduce symptoms if the neck is the source. Cervical imaging and careful neurological testing — checking specific reflex changes, dermatomal sensation maps, and myotomal weakness patterns — help clarify the picture. A patient with C6 radiculopathy may also have neck pain, shoulder blade discomfort, or symptoms that travel up the arm rather than being localized to the wrist.
Treating the wrist of a patient with cervical radiculopathy may not be the course of action.
Thoracic Outlet Syndrome (TOS)
The brachial plexus — the nerve bundle that eventually becomes the median, ulnar, and radial nerves — passes through a narrow space between your collarbone, first rib, and scalene muscles in the neck. Compression here can produce arm, forearm, and hand symptoms that mimic both CTS and cervical radiculopathy. TOS is often missed because it requires specific provocative tests (Roos test, EAST position) and because many practitioners don't think to look for it.
People who sit with forward head posture and rounded shoulders for hours a day — i.e., most desk workers — are prime candidates.
Pronator Teres Syndrome
This one stays closer to the wrist diagnosis but is still not CTS. The median nerve can also be compressed as it passes through the pronator teres muscle in the forearm, just below the elbow. Unlike true CTS, pronator teres syndrome tends to produce forearm aching alongside the hand tingling, and provocation with resisted forearm pronation (or resisted middle finger flexion) will often reproduce symptoms. Phalen's test — the classic CTS test where you hold wrists flexed for 60 seconds — is usually negative.
Double Crush Syndrome
This one is worth understanding because it's underappreciated and explains why some CTS cases don't fully resolve even after surgical release. The concept: a nerve that is already irritated or compressed at one point along its course becomes hypersensitive to compression at a second point. Someone with mild cervical nerve root irritation may develop true CTS symptoms at the wrist because the nerve's overall tolerance for compression is reduced. Treating just the wrist gives partial relief. You have to treat both sites.
So How Do We Know It's Actually CTS?
Confirmed CTS has several hallmarks that, together, build a convincing clinical picture:
A positive Phalen's test (symptoms reproduced within 60 seconds of sustained wrist flexion) and positive Tinel's sign (tapping over the carpal tunnel reproduces tingling in the median nerve distribution) are the classic bedside tests. Neither is perfect in isolation, but together they have reasonable diagnostic accuracy.
Nerve conduction studies (NCS) remain the gold standard for confirming median nerve slowing at the wrist. If there's any diagnostic ambiguity, especially before considering surgery, these should be done.
The symptom distribution should fit: thumb, index, middle, and radial half of the ring finger. If the little finger is involved (ulnar nerve territory), we're dealing with something else — possibly cubital tunnel syndrome at the elbow.
And the symptom pattern matters: classic CTS is worse at night (because the wrist often falls into flexion during sleep) and with sustained wrist flexion (typing, driving, holding a phone). Symptoms that are positional in a different way, or that are provoked more by neck movement than wrist position, point elsewhere.
Can It Be Treated Without Surgery?
For most people, yes. And I want to be clear about this because surgery tends to be framed as the inevitable destination — especially for patients who've been symptomatic for a while.
The evidence supports conservative management as the appropriate first approach for mild to moderate CTS. That includes:
Splinting in a neutral wrist position — particularly at night — reduces the sustained wrist flexion that compresses the nerve during sleep. This alone often produces significant symptom relief within a few weeks.
Manual therapy — including joint mobilization of the wrist and cervical spine, soft tissue work to the forearm and carpal structures, acupuncture/dry needling and neurodynamic techniques (median nerve gliding) — has evidence behind it for improving symptoms and nerve mobility.
Corticosteroid injection can provide meaningful short-term relief and is a reasonable option when symptoms are moderate and the patient needs a faster response. It is not a long-term solution on its own. I send clients to trusted allied health professionals to determine if this is warranted.
Exercise and progressive loading is where most conservative care programs fall short — and where things go wrong. The median nerve runs through a tunnel that is surrounded by tendons and their sheaths. If those tendons are weak, inflamed, or poorly conditioned, they take up more space in the tunnel. Building wrist and hand strength — flexors, extensors, intrinsic muscles — reduces tissue volume, improves tendon health, and creates a more resilient local environment for the nerve.
Rest without progressive loading is not a solution. It's a delay. The patient who splints for six weeks and then returns to the same wrist-intensive work without any change in tissue capacity will be back in my office with the same problem.
Surgery (carpal tunnel release) is appropriate for moderate to severe CTS that has failed a genuine trial of conservative care, or where there is muscle wasting in the thenar eminence indicating significant nerve compromise. The outcomes are generally very good. But it's not where most cases should start.
A Note on Why Therapy and Training Together Matter
This is the point I make to almost every patient I see with CTS or CTS-like symptoms: manual therapy gets the tissue and nervous system ready; exercise makes the change stick.
What I do in the treatment room — releasing tight forearm musculature via soft tissue work and acupuncture/dry needling, using other modalities such as shockwave, mobilizing stiff wrist joints, working on cervical mechanics if there's a neck component, improving median nerve mobility — creates a window of improved tissue environment. That window needs to be used. Education and engaged discussion with clients is also deeply important.
If someone leaves my office and goes straight back to eight hours of uninterrupted keyboard work without any strengthening, mobility, or loading work at home, the benefit of the session erodes quickly. The tissues haven't changed. The capacity hasn't changed. The only thing that changed was temporary.
The patients who recover fastest and most completely are the ones who combine in-office treatment with a structured training program at home. Building wrist and hand strength — specifically, progressively — is what turns a temporary improvement into a lasting one. It's what keeps people out of my office and off the surgical waitlist.
What to Do If You Think You Have CTS
First: get assessed by someone who will actually do a differential diagnosis. Don't accept "sounds like carpal tunnel, here's a brace" as an answer. The stakes are too high. If the problem is in your neck and someone operates on your wrist, nothing gets better — and you've now had unnecessary surgery.
Second: understand that rest alone is not a treatment plan. Your nervous system and connective tissue need progressively increasing input to adapt. Bracing your wrist at night is a tool; it is not a program.
Third: ask about the training component. Conservative care that includes progressive wrist and hand strengthening has better long-term outcomes than passive care alone. If your practitioner isn't talking about what you're doing between sessions, ask the question.
At Vital Performance Care, we work collaboratively across disciplines precisely because hand and wrist problems rarely have a single cause or a single solution. Assessment, treatment, and training — done in sequence and in parallel — is how people actually get better.
