Carpal Tunnel Syndrome

Carpal tunnel syndrome physiotherapy may help if you have night-time tingling, numb fingers, hand weakness, or wrist pain that flares with typing, gripping, driving, or tool use. Carpal tunnel syndrome happens when the median nerve becomes irritated or compressed as it passes through a tight space at the wrist. Early care often focuses on calming symptoms, reducing pressure on the nerve, and restoring comfortable hand use.

For broader guidance on related problems, see our Hand & Wrist Pain hub and our Nerve Pain guide. If your symptoms may relate to the neck or upper limb, read about pinched nerve and cervical radiculopathy.

What is carpal tunnel syndrome?

Carpal tunnel syndrome describes a pattern of symptoms caused by irritation of the median nerve at the wrist. Many people notice tingling or numbness in the thumb, index, and middle fingers, plus night pain, hand weakness, or dropping objects. Symptoms may build slowly, then flare during heavier weeks at work, sport, DIY, or prolonged device use.

The anatomy of your carpal tunnel

The carpal tunnel is a narrow passage formed by wrist bones and a strong ligament called the transverse carpal ligament. It contains the flexor tendons and the median nerve. Swelling in the tunnel, tendon irritation, or sustained wrist bending can increase pressure and disturb nerve function.

Causes and risk factors

Carpal tunnel syndrome often relates to a mix of factors rather than one single cause. Common contributors include repetitive or sustained wrist positions, gripping loads, swelling including during pregnancy, inflammatory conditions, and workplace vibration exposure. Some people also appear to have a naturally tighter carpal tunnel shape.

Symptoms of carpal tunnel syndrome

Symptoms usually affect the thumb side of the hand and often build up over time. Common signs include:

tingling or numbness in the thumb, index, and middle fingers
night pain or waking with a “dead” hand
hand weakness, clumsiness, or reduced pinch grip
symptoms that flare with driving, typing, gripping, or tool use

Why does carpal tunnel syndrome hurt more at night?

Many people find symptoms are worse at night because the wrist often stays bent for longer while sleeping. That position can increase pressure inside the carpal tunnel and irritate the median nerve. Night splints often aim to keep the wrist closer to neutral so symptoms settle more easily.

“Double crush” and symptoms beyond the wrist

Sometimes, similar symptoms come from nerve irritation higher up the arm or neck. Clinicians often call this a “double crush” pattern. That is why a physiotherapist will usually screen the neck, shoulder, and elbow, not just the wrist. If you also have neck pain or arm symptoms, this may change your treatment plan.

Neurodynamics and nerve movement

Nerves need to slide and tolerate movement. If surrounding tissues restrict that glide, symptoms can feel sharper, more widespread, or more easily triggered. A physiotherapist may use gentle nerve movement testing and guide graded nerve gliding work. For more background, see our Neurodynamics page.

How is carpal tunnel syndrome diagnosed?

Diagnosis usually starts with your symptom pattern and a physical examination. Common in-clinic tests include Phalen’s test and Tinel’s sign. Your physiotherapist may also check sensation, thumb strength, grip, and whether the neck or upper limb are contributing. In some cases, your GP may request nerve conduction studies or ultrasound to confirm severity or rule out other causes.

Physiotherapy treatment for carpal tunnel syndrome

Treatment aims to reduce pressure on the median nerve and improve how your hand copes with daily loads. A physiotherapist may recommend:

wrist positioning advice, especially at night and during longer tasks
graded nerve and tendon gliding exercises
gentle joint and soft tissue techniques where suitable
ergonomic changes for keyboard, mouse, tools, and lifting
strength and capacity work for the hand, forearm, and shoulder as symptoms settle

The role of night splints

Night splints aim to keep the wrist closer to neutral so the nerve stays under less pressure while you sleep. Many people find night splints reduce waking symptoms. Your physiotherapist can help you choose a splint style and fit, then show you how to use it without over-tightening.

Kinesiology tape

Kinesiology tape may suit some people as a short-term support, particularly during aggravating tasks. A physiotherapist may use taping to cue wrist position and manage irritability while you build longer-term capacity. If tape causes skin irritation, stop and discuss alternatives.

Can carpal tunnel syndrome go away on its own?

Mild carpal tunnel syndrome can settle, especially when symptoms relate to a temporary increase in swelling or workload. However, persistent night symptoms, worsening numbness, or growing weakness should be assessed, because longer-lasting nerve compression can lead to slower recovery.

When should you worry about carpal tunnel syndrome?

You should arrange an assessment if symptoms keep waking you at night, spread through the hand, or start affecting grip, pinch, or fine control. Progressive weakness, constant numbness, or visible muscle wasting around the thumb need prompt review because they may suggest more significant nerve compression.

Surgery and injections

If symptoms are severe, persistent, or include ongoing weakness or muscle wasting, your clinician may discuss injection or surgical options. Before making decisions, it helps to confirm that symptoms are not mainly driven by another site such as the neck or more proximal nerve irritation, because that can change outcomes and planning.

Prevention and recurrence control

Many flare-ups improve when you address the main drivers: wrist position, repetitive load, gripping intensity, recovery breaks, and strength.

FAQs about carpal tunnel syndrome

What are the main symptoms of carpal tunnel syndrome?

Common symptoms include tingling or numbness in the thumb, index, and middle fingers, night pain, and waking with a numb or “dead” hand. Some people also notice weaker grip, poorer pinch strength, or clumsiness with buttons, jars, or small objects.

How do you know if it is carpal tunnel syndrome or a pinched nerve in the neck?

Carpal tunnel syndrome often focuses on the thumb-side fingers and may worsen at night or with wrist-heavy tasks. Neck-related nerve irritation can include neck pain, shoulder or arm symptoms, and changes with neck positions. A physiotherapist can screen both areas and explain which pattern fits best.

Do night splints help carpal tunnel syndrome?

Night splints may help reduce symptoms by keeping the wrist closer to neutral while you sleep. Many people find they wake less often with tingling or numbness when the splint fits well and is not too tight. A physiotherapist can guide the best fit and timing.

What exercises help carpal tunnel syndrome?

Exercises may include graded nerve gliding, tendon gliding, and later strength work for the hand, forearm, and shoulder. The best program depends on how irritable your symptoms are and what loads trigger them. A physiotherapist can adjust the dosage so you do not flare the nerve.

When is surgery considered for carpal tunnel syndrome?

Surgery may be considered when symptoms are severe, persistent despite conservative care, or linked to progressive weakness, constant numbness, or muscle wasting. Your clinician may recommend nerve testing or specialist review to help confirm severity and guide the next step.

What to do next

If you have night-time numbness, worsening tingling, or reduced hand strength, book an assessment sooner rather than later. A physiotherapist can check whether your symptoms match carpal tunnel syndrome, screen your neck and upper limb, and explain a practical plan. If your symptoms suggest higher risk, such as progressive weakness, constant numbness, or major loss of function, they may recommend GP review or nerve testing.
