Carpal Tunnel Syndrome: Why Your Hand Goes Numb at Night

Carpal tunnel syndrome (CTS) is a condition in which the median nerve becomes compressed as it passes through a narrow passage in the wrist called the carpal tunnel. This nerve gives sensation to the thumb, index finger, middle finger and part of the ring finger, and controls important muscles at the base of the thumb. When pressure on the nerve persists, the hand develops numbness, tingling, pain and weakness.

It is one of the most common nerve compression disorders we see in Jalandhar, and one of the most frequently ignored — largely because the early symptoms come and go.

Symptoms

The condition usually develops gradually. Early symptoms often appear at night and may wake a person from sleep. Patients describe tingling, numbness, burning or an electric-shock sensation in the thumb, index, middle and part of the ring finger. Symptoms can also appear while holding a phone, a book or a steering wheel. Many people instinctively shake the hand to get relief.

As it progresses, numbness becomes persistent and grip strength declines. Buttoning clothes, writing, opening containers and holding small objects become difficult, and people start dropping things. Severe or prolonged compression causes wasting of the muscles at the base of the thumb.

Symptoms in the little finger are not typical of carpal tunnel syndrome, because the median nerve does not supply that finger. Numbness involving the little finger points to a different nerve or a neck problem and needs separate assessment.

Who is at risk

CTS can occur without one identifiable cause, but several factors raise the risk. Women are affected more often than men, partly because the carpal tunnel is generally smaller. Risk also rises with age, obesity, diabetes, thyroid disorders, rheumatoid arthritis, pregnancy and conditions causing fluid retention. Previous wrist fractures or other structural changes narrow the tunnel further.

Work involving repeated, forceful hand movements is a major risk factor. A recent systematic review found high exposure to repetitive movement and high hand-force intensity associated with substantially greater rates of work-related CTS. Prolonged gripping, assembly work, cleaning, construction and sewing all place sustained stress on the wrist.

Computer use deserves a more careful explanation than it usually gets. Prolonged computer work can certainly cause hand and wrist discomfort, but current evidence does not establish ordinary keyboard use as a major direct cause of CTS. Repetitive forceful movements and sustained awkward wrist positions have far stronger evidence behind them.

Why the burden is high in Punjab

Jalandhar and the surrounding districts combine several risk environments at once.

Research from Indian clinical populations has found a substantial representation of women doing housework and hand-intensive manual work — cleaning, cooking, tailoring, kneading. In one Indian study of 454 patients with CTS, 191 were housewives, and female manual workers and housewives had more severe symptoms and greater clinical and electrophysiological abnormality than female non-manual workers.

Punjab also has large numbers of people in occupations involving repetitive manual activity — sports goods manufacturing, hand tools, leather work, textile and hosiery units, and farm work. Recent research on Indian carpet weavers highlights prolonged work in awkward postures as a significant occupational concern, and the same pattern applies across much of this region's small-scale manufacturing.

Metabolic health compounds it. Diabetes is associated with increased vulnerability to nerve compression, and Punjab has a high diabetes burden. The combination of diabetes, obesity, repetitive manual work and low awareness means many patients here reach a doctor only once numbness has become constant.

How it is diagnosed

Diagnosis begins with a clinical examination of sensation, grip and thumb muscle strength. Where the picture is unclear or surgery is being considered, nerve conduction studies, electromyography or ultrasound confirm both the diagnosis and the severity. Severity matters, because it determines whether splinting is reasonable or whether surgery is the better option.

Which treatments work

Treatment depends on severity and duration.

Mild, intermittent CTS. Night-time wrist splinting is usually a sensible first step. A splint holds the wrist neutral and reduces pressure on the median nerve. A 2023 Cochrane review found evidence supporting splinting as a treatment option, though the certainty of evidence varied across outcomes. Reducing aggravating activities, taking regular breaks from repetitive work and correcting wrist position all help. Hand or occupational therapy can add activity modification, exercises and nerve-gliding techniques.

Corticosteroid injection. Useful for short-term relief when symptoms are troublesome but surgery is not yet warranted. Recent evidence suggests the benefit is usually temporary — a 2024 network meta-analysis found only modest short-term improvement compared with splinting or placebo, without clinically important differences across several key outcomes.

Surgery. For severe CTS, persistent numbness, significant weakness, muscle wasting, or symptoms not responding to conservative treatment, carpal tunnel release is the better option. The procedure divides the transverse carpal ligament to create more space for the nerve. Both open and endoscopic techniques are used. A 2024 systematic review and meta-analysis also found significant improvement in validated measures of sleep quality and insomnia after carpal tunnel release — which matters, because disturbed sleep is one of the things patients find hardest to live with.

Mistakes that cost people their hand function

The most common is ignoring numbness because it comes and goes. Prolonged compression causes permanent nerve and muscle damage. Once the thumb muscles have wasted, surgery relieves pain and stops progression but may not fully restore what was lost.

The second is assuming every wrist or hand problem is CTS. Tendon disorders, arthritis, cervical nerve compression and other nerve entrapments produce similar symptoms and need different treatment.

The third is relying on painkillers as a long-term solution. Medicines may reduce discomfort but do not remove the compression, and there is no evidence that common pain relievers improve the condition itself.

What you can do yourself

• Keep the wrist neutral during sleep — this is when most people's symptoms peak
• Take frequent breaks from repetitive tasks rather than pushing through
• Adjust keyboard height and position; reduce forceful gripping; alternate tasks where possible
• Keep diabetes and thyroid disease well controlled
• Maintain a healthy weight

Carpal tunnel treatment at Oxford Hospital Jalandhar

Our orthopaedic team assesses carpal tunnel syndrome with clinical examination and, where needed, nerve conduction studies, so treatment is matched to the actual severity of nerve compression rather than to symptoms alone. Splinting, activity modification, injection and carpal tunnel release are all available, and the decision between them is made on findings, not on preference.

Treatment is cashless under PMJAY, CGHS, ECHS and major insurers. If you have had night-time numbness in the hand for more than a few weeks, get it assessed before grip weakness starts — that is the point at which outcomes change.

This article has been medically researched and reviewed using clinical sources and recent peer-reviewed research, but it should not be taken as medical advice or used as a substitute for examination by a qualified healthcare professional. If you are experiencing persistent numbness, tingling, pain or weakness, please see a doctor for diagnosis and a treatment plan.
