You wake at 3 am with your hand completely numb. You shake it out, the feeling slowly returns, and you go back to sleep — until it happens again. That pattern, more than almost any other symptom, points to carpal tunnel syndrome.
Carpal tunnel syndrome is the most common peripheral nerve compression condition in Singapore and worldwide. It is also one of the most misunderstood — because the problem at the wrist is often only part of the story.
What is carpal tunnel syndrome?
The carpal tunnel is a narrow passageway on the palm side of your wrist. Its floor and walls are formed by eight small carpal bones; its roof is a thick band of connective tissue called the transverse carpal ligament. Running through this tunnel are nine flexor tendons — the cables that curl your fingers — and, sharing that tight space, the median nerve.
When the tunnel becomes crowded — through swelling, inflammation, fluid retention, or structural change — the median nerve is the first to suffer. That nerve is responsible for sensation to the thumb, index finger, middle finger, and the thumb-side half of the ring finger, as well as the small muscles at the base of the thumb that allow precise pinching and gripping. When it is compressed, those functions break down.
What causes carpal tunnel syndrome?
Several factors can increase pressure inside the carpal tunnel:
- Repetitive wrist loading. Prolonged keyboard use, mousing, or any task that keeps the wrist in sustained flexion or extension raises tendon pressure and provokes inflammation inside the tunnel over time. This is the most common presentation in Singapore’s office-working population.
- Fluid retention. Pregnancy, hypothyroidism, and kidney disease all cause the body to retain fluid — including inside the carpal tunnel. Symptoms during pregnancy often resolve after delivery.
- Diabetes. Elevated blood glucose damages peripheral nerves and makes them more vulnerable to compression at any site, including the wrist.
- Structural change. A previous wrist fracture that healed slightly out of alignment, or arthritis altering the shape of the tunnel, can reduce available space.
- Inflammatory arthritis. Rheumatoid arthritis causes synovial tissue proliferation that can directly crowd the tunnel.
That said, in a significant proportion of people — particularly those who present without obvious risk factors or whose symptoms are asymmetric and inconsistent — the wrist is not the only place the median nerve is under pressure.
Recognising carpal tunnel syndrome: symptoms and signs
The classic presentation is straightforward once you know what to look for:
- Numbness and tingling in the thumb, index, and middle fingers. The little finger is not affected — that is a different nerve (the ulnar nerve). If the little finger is involved, the compression is likely elsewhere.
- Symptoms that are worst at night or first thing in the morning. Lying with the wrist bent — which most people do unconsciously during sleep — maximises tunnel pressure. Waking up needing to shake the hand out is the hallmark symptom.
- Symptoms that worsen with sustained gripping. Driving, holding a phone, or carrying a bag can all provoke symptoms.
- Weakness in grip and pinch. Buttoning a shirt, opening jars, or picking up small objects becomes difficult.
- Pain that radiates up the forearm. Some people feel aching up into the elbow or even the shoulder — not because the compression is there, but because an irritated nerve can generate pain along its length.
Signs that something more serious may be going on
See a doctor promptly if you notice visible wasting of the muscle at the base of your thumb (the thenar eminence becomes flat), if you have complete loss of feeling in the fingers, or if you are dropping objects you would not normally drop. These suggest advanced nerve compression that may require urgent surgical evaluation. Similarly, if you have known diabetes, thyroid disease, or rheumatoid arthritis, managing the underlying condition is part of any effective approach.
The double crush: why the neck is often part of the picture
The median nerve does not begin at the wrist. It originates from nerve roots at the C6 and C7 levels of the cervical spine — the lower neck — and travels through the shoulder, down the arm, through the forearm, and into the hand before passing through the carpal tunnel.
A nerve under low-level stress anywhere along its course becomes more vulnerable to compression at any other point. This is known as the double crush phenomenon: a minor degree of compression in the neck or at the thoracic outlet (between the collarbone and first rib) may not be enough to cause symptoms on its own, but combined with even mild compression at the wrist, the two add up to produce clear symptoms.
This explains a pattern that clinicians see regularly: people whose carpal tunnel symptoms fail to respond to wrist splinting alone, or who continue to have symptoms after carpal tunnel release surgery. When the cervical spine is not assessed and addressed, the nerve remains under load from above.
It also explains why some people with no particular wrist injury, no fluid retention, and no obvious local cause end up with classic carpal tunnel symptoms — the compression is primarily higher up the chain, and the wrist is where it becomes symptomatic.
For office workers with neck and upper back pain who also notice hand tingling, this connection is especially worth investigating.
Carpal tunnel syndrome vs. a pinched nerve in the neck
These two conditions overlap in their symptoms and are frequently confused. The key differences:
- Pattern of numbness. Carpal tunnel affects the thumb, index, and middle fingers. A C6 nerve root compression affects a similar distribution but typically also involves the thumb-side of the forearm. A C7 compression affects the middle finger and forearm differently. If the little finger is numb, the problem is more likely ulnar nerve or C8.
- Neck symptoms. A pinched nerve in the neck usually — though not always — produces some neck pain, stiffness, or pain that travels from the neck into the shoulder and arm. Pure carpal tunnel rarely involves the neck itself.
- Provocative positions. Symptoms that worsen with neck movement or looking upward suggest a cervical origin. Symptoms that worsen with wrist flexion (the Phalen test) or tapping over the wrist (the Tinel test) point more toward the tunnel.
- Time of onset. Night symptoms waking you from sleep strongly favour CTS, since the wrist position during sleep is the aggravating factor.
In practice, both can coexist — and often do. This is why a thorough assessment that covers the entire nerve pathway, from neck to fingertip, produces better outcomes than treating only the wrist.
The same principle applies to sciatica, where leg pain is the symptom but the compression can be at the spine, the piriformis, or both.
What does chiropractic care for carpal tunnel involve?
At Family Health Chiropractic Clinic, Dr Kelvin Ng (Founder and Clinic Director) and Dr Ashley Liew (Senior Associate Chiropractor) assess the full nerve pathway — not just the wrist. This means examining the cervical spine for restricted movement or joint dysfunction at C5–C7, assessing the shoulder and thoracic outlet for muscular or structural factors that may be loading the nerve, and evaluating the wrist itself.
FHCC uses ArthroStim instrument-assisted adjusting exclusively — a precise, low-force instrument technique. The ArthroStim delivers a controlled, rapid series of impulses to the targeted joint segment, achieving joint mobilisation without the high-velocity rotational thrust of traditional manual adjusting. This makes it suitable for the delicate structures of the cervical spine as well as the small joints of the wrist and hand.
For carpal tunnel presentations with a cervical component, addressing joint restriction at C6–C7 reduces the mechanical load on the nerve at its origin. For presentations that are predominantly local to the wrist, the approach focuses on the carpal bones and surrounding soft tissue. For most people, some combination of both is relevant.
Alongside adjusting, the assessment typically includes ergonomic guidance — keyboard height, mouse position, wrist angle during typing — since sustained poor positioning continues to load the tunnel even if the joint mechanics improve. Where night symptoms are prominent, a neutral wrist splint worn during sleep is often helpful as an adjunct.
When surgery is the right answer
Carpal tunnel release is a highly effective procedure when it is the right intervention for the right patient. If the compression is confirmed to be at the wrist, is of significant severity (confirmed on nerve conduction study), and conservative care has not produced adequate improvement, surgical consultation is appropriate. Dr Kelvin Ng and Dr Ashley Liew will advise referral when that is the right step — the goal is the best outcome for the person, not exhausting conservative options indefinitely.
What to expect at Family Health Chiropractic Clinic
At the initial consultation, Dr Kelvin Ng or Dr Ashley Liew will take a detailed history of your symptoms — when they started, what aggravates and relieves them, whether there is any neck component, and what other health factors may be relevant. This is followed by a physical examination of the neck, shoulder, elbow, and wrist, including standard provocation tests for carpal tunnel.
If the presentation is straightforward, care typically begins at the first visit. If the examination raises questions — for example, if the nerve distribution does not fit cleanly, or if there are features suggesting something other than mechanical compression — you will be referred for appropriate investigation before proceeding.

Frequently asked questions
What is carpal tunnel syndrome?
Carpal tunnel syndrome is compression of the median nerve as it passes through the carpal tunnel — a narrow passageway at the base of the palm formed by the wrist bones and the transverse carpal ligament. The compression causes numbness, tingling, and weakness in the thumb, index, and middle fingers. It is the most common peripheral nerve entrapment condition, most often affecting people who perform repetitive hand and wrist movements.
Can a chiropractor help with carpal tunnel syndrome in Singapore?
Yes — particularly when there is a cervical spine or thoracic outlet component contributing to the symptoms. The median nerve originates at the C6–C7 levels of the neck, and tension or restriction anywhere along its course can amplify compression at the wrist (the “double crush” phenomenon). Chiropractic assessment looks at the whole nerve pathway, not just the wrist, and instrument-assisted adjusting can address joint dysfunction in the neck and wrist without high-velocity thrusting. For purely local wrist compression, chiropractic is one of several conservative options alongside splinting and physiotherapy; for cases with a neck component, it is often the most targeted approach.
How is carpal tunnel syndrome different from a pinched nerve in the neck?
Both can cause numbness and tingling in the hand, but the patterns differ. Carpal tunnel affects the thumb, index, and middle fingers, and symptoms are classically worst at night or during sustained wrist flexion. A cervical nerve root compression (radiculopathy) typically also involves some neck stiffness or arm pain starting from the neck, and the distribution of numbness may extend further up the forearm. The two conditions frequently coexist — a stiff neck can lower the threshold for carpal tunnel symptoms at the wrist, and vice versa. A thorough physical examination distinguishes them and identifies when both need to be addressed.
Do I need surgery for carpal tunnel syndrome?
Not in most cases, particularly when symptoms are mild to moderate and have not been present for years. Carpal tunnel release surgery has a high success rate when the diagnosis is confirmed by nerve conduction study and the compression is specifically at the wrist. However, conservative management — wrist splinting, activity modification, addressing cervical spine involvement, and sometimes steroid injection — is the appropriate first step for the majority of people. Surgery becomes the right answer when conservative care has been genuinely tried and has not achieved adequate improvement, or when there is significant nerve damage (muscle wasting, severe loss of sensation) that requires urgent intervention.
How long does it take to improve with chiropractic care for carpal tunnel?
It depends on how long the nerve compression has been present and whether there is a cervical component. For early-stage presentations — a few months of symptoms, no muscle wasting, symptoms that come and go — meaningful improvement is typically seen within four to eight visits over three to six weeks. Long-standing compression where the nerve has been under sustained load takes longer to settle. If a cervical component is identified and addressed, some people notice a surprising improvement in hand symptoms quite quickly, as the total nerve load is reduced. Progress is reassessed at each visit, and care is adjusted based on how you are responding.
