Carpal Tunnel Syndrome: Symptoms, Treatment and When to See a Physio

Tingling fingers, a numb hand at night or a weaker grip can make sleep, driving and everyday tasks difficult. These are common features of carpal tunnel syndrome, caused by pressure on the median nerve as it passes through the wrist. Symptoms can settle, but they may take months, so early, sensible management matters.

What is carpal tunnel syndrome?

The carpal tunnel is a narrow passage on the palm side of the wrist. The median nerve and several tendons travel through it. If pressure builds inside the tunnel, the nerve can become irritated or compressed.

According to the NHS guidance on carpal tunnel syndrome, symptoms often begin gradually, come and go, and feel worse at night. They may affect one or both hands.

Common symptoms

• tingling or pins and needles in the hand or fingers;
• numbness, especially at night or on waking;
• an ache or pain that can extend into the hand or arm;
• a weak thumb or reduced grip, sometimes making you drop objects;
• symptoms triggered by sustained gripping or repeated wrist positions.

These symptoms are not unique to carpal tunnel syndrome. A nerve problem in the neck, another hand condition or a medical condition can feel similar. A proper assessment is therefore more useful than relying on an online checklist alone.

Why does it happen?

Sometimes there is no single cause. Risk is higher during pregnancy and in people with diabetes, arthritis, a previous wrist injury or a family history of the condition. Work or hobbies involving repeated wrist bending, forceful gripping or vibrating tools can also aggravate symptoms. Being overweight is another recognised risk factor.

Typing can provoke symptoms for some people, but discomfort at a keyboard does not automatically mean the job caused nerve compression. The pattern, severity and physical findings all matter.

What can you try at home?

1. Keep the wrist straighter at night

A neutral-position wrist splint worn at night can reduce pressure on the nerve. The NHS advises that it may take up to six weeks before you notice improvement. The splint should feel supportive, not painfully tight, and should not increase numbness or alter the colour of your fingers.

2. Adjust aggravating activities

Temporarily reduce tasks that repeatedly bend the wrist, demand hard gripping or use vibrating tools. At a desk, aim for a comfortable forearm position, vary tasks and take short movement breaks. You do not usually need to stop all activity; the goal is to reduce repeated provocation while keeping the hand moving comfortably.

3. Use exercise carefully

Gentle wrist and finger movements may help some people, although the NHS notes that evidence for exercises is limited. The Chartered Society of Physiotherapy provides simple wrist and finger exercises, but one routine will not suit everyone. Stop an exercise if it clearly increases tingling, numbness or pain and the symptoms do not quickly settle.

4. Be realistic about pain relief

Paracetamol or ibuprofen may ease pain for a short time, but the NHS says there is little evidence that they treat the underlying cause. Check with a pharmacist or GP if you are unsure whether a medicine is safe for you, particularly if you are pregnant, take other medicines or have another health condition.

How can physiotherapy help carpal tunnel syndrome?

A physiotherapist can listen to the history, examine wrist and hand movement, check sensation and strength, and look for signs that symptoms may come from elsewhere. Management may include:

• advice on sleep, work, driving and aggravating activities;
• guidance on choosing and using a wrist splint;
• a tailored movement or exercise programme;
• monitoring grip, thumb strength and sensory changes;
• referral to a GP or specialist when the findings suggest tests or medical treatment are needed.

Will I need tests, an injection or surgery?

Typical carpal tunnel syndrome can often be diagnosed from the history and examination. Nerve conduction tests or imaging may be considered when the diagnosis is uncertain, symptoms are persistent or treatment decisions need more information.

If a night splint and activity changes do not help, a GP may discuss a steroid injection. This can reduce symptoms, but they may return. When symptoms are worsening, weakness is developing or other treatment has failed, referral for carpal tunnel release surgery may be appropriate.

The NHS describes surgery as a short outpatient procedure and says people usually return to normal activities in about a month. Recovery varies with the type of work, symptom severity and how long the nerve has been affected. Long-standing numbness or weakness may not disappear immediately, so avoid guarantees about a fixed recovery date.

When should you seek medical advice?

Arrange a GP or clinical assessment if symptoms are getting worse, are not going away, or have not improved with home treatment. Seek assessment promptly if you notice:

• persistent or increasing numbness;
• new hand or thumb weakness;
• frequent dropping of objects or loss of fine hand control;
• visible wasting at the base of the thumb;
• symptoms that are severe, rapidly changing or affecting both hands alongside other neurological symptoms.

Weakness or muscle wasting can suggest more significant nerve compression. Early medical review helps protect hand function and identifies people who may need specialist treatment.

What to expect from recovery

Mild, intermittent symptoms may improve over several weeks with a suitable night splint and changes to aggravating activities. Other cases take months. Improvement is not always linear: a busy day, poor sleep or prolonged gripping can cause a temporary flare without meaning that all progress has been lost.

If symptoms remain constant, strength declines or there is little change after a reasonable trial of self-management, reassessment is sensible. The next step may be a different diagnosis, a better-fitted splint, medical treatment or specialist referral rather than simply doing more exercises.
