Carpal tunnel syndrome – symptoms, causes and treatment

Carpal tunnel syndrome is the most common nerve entrapment in the hand. In the narrow tunnel of the wrist the median nerve (n. medianus) comes under pressure, causing tingling, numbness and pain in the thumb, index and middle fingers – often at night or during computer work. Tight muscles in the forearm, shoulder and neck, through which the nerve runs, can also aggravate and mimic these symptoms. That is why we always assess the whole nerve pathway from the neck to the fingers and choose suitable muscle and joint work.
Carpal tunnel syndrome – symptoms, causes and treatment

When to see a doctor or call 112

  • Call 112 if weakness or numbness in the arm comes on suddenly together with facial numbness or disturbed speech or vision.
  • Constant numbness that does not ease even with rest, or visible wasting of the thumb muscles, needs a doctor's assessment and a nerve conduction study.
  • Rapidly increasing hand weakness – constantly dropping things – needs a doctor's assessment.
  • Numbness or pain after a wrist injury or fall – see a doctor straight away.

How carpal tunnel syndrome shows up

Night-time symptoms

The most typical start: the fingers tingle or go numb at night and you wake up. Shaking or moving the hand brings relief. At night the wrist is often bent for long periods, which raises the pressure in the tunnel.

Symptoms during the day and at work

Tingling and numbness appear when using a mouse, phone, steering wheel or tools. Fine motor skills become clumsier and grip strength drops – doing up buttons or opening a jar gets harder.

Longer-lasting symptoms

When symptoms continue for months, they become more frequent and persistent. The earlier the muscle tension and nerve mobility are addressed, the easier it is to relieve the symptoms.

Symptoms that resemble carpal tunnel syndrome

Similar tingling and referred pain can come from trigger points in the forearm, shoulder and neck muscles and from nerve tension higher along its course. So we do not stop at the wrist but also assess the forearm, shoulder and neck.

Muscles linked to hand numbness and wrist pain

According to the classic description of myofascial pain (Travell and Simons), each muscle has its own typical referred pain pattern. Pain and tingling from several muscles radiate to the wrist and fingers and resemble carpal tunnel syndrome. The patterns are a guide, not a diagnosis.

Wrist flexors (m. flexor carpi radialis et ulnaris)

Bend the wrist. Referred pain to the palm side of the wrist and the wrist crease. Overloaded by gripping, mouse use and working with tools.

Superficial and deep finger flexors (m. flexor digitorum superficialis et profundus)

Bend the fingers; their tendons pass through the carpal tunnel together with the median nerve. Pain and tingling radiate to the fingers. Tight muscles and tendons increase the crowding in the tunnel.

Pronator teres

Turns the forearm palm down. The median nerve passes through this muscle, so tension in it can cause tingling in the same fingers as the carpal tunnel. Referred pain to the forearm and the thumb side of the wrist.

Brachialis

Bends the elbow. Referred pain to the base of the thumb and the thumb pad – often mistaken for a wrist problem.

Scalenes (mm. scaleni)

Muscles on the side of the neck between which the nerves of the arm run. Pain and tingling can radiate to the upper arm, outer forearm, thumb and index finger.

Pectoralis minor

Pulls the shoulder forward. The nerves and vessels of the arm run beneath it; a tight muscle can cause tingling and heaviness in the whole arm.

Thenar muscles (eminentia thenaris)

Move and oppose the thumb. Typical pain at the base of the thumb and in the wrist. Overloaded by phone use and fine manual work.

Why the hand tingles and goes numb

Pressure in the carpal tunnel. The median nerve passes through the narrow tunnel of the wrist together with nine finger flexor tendons. When the pressure in the tunnel rises, the nerve's blood supply is reduced and tingling, numbness and pain appear.[1]

Wrist position and repetitive load. A wrist held bent or extended for long periods, a computer mouse, phone, vibrating tools and a strong grip raise the pressure in the tunnel and load the forearm muscles.

Muscle tension and trigger points. Tight muscles in the forearm, shoulder and neck cause referred pain and tingling and may restrict the free gliding of the nerve during movement. One study found trapezius trigger points in a large share of people with carpal tunnel symptoms.[7]

Swelling of the tissue around the tendons. Morning swelling and thickening of the tissue around the tendons reduce the space in the tunnel and increase the pressure on the nerve.

The nerve along its whole course. The median nerve runs from the neck through the shoulder and forearm to the wrist. If the nerve is under tension in several places, symptoms are stronger – so we work along its whole course, not only at the wrist.

How our methods may help

Trigger point therapy

We treat trigger points in the wrist and finger flexors, pronator teres, brachialis, scalenes and pectoralis minor. The aim is to reduce referred pain and tingling and free up the nerve pathway.

Medical massage

Working on the forearm, shoulder and neck muscles reduces muscle tension, improves blood supply and relieves pain and numbness. In a study, massage combined with trigger point therapy has produced clear improvement.[3]

Manual therapy and mobilisation

Mobilisation of the wrist bones, elbow and neck–upper back, together with techniques that improve nerve gliding, help reduce pressure and restore mobility. Before manual therapy we always carry out an assessment and tests.

Ultrasound therapy

Ultrasound acts on the tissues around the tunnel, helps reduce swelling and relieves symptoms. In a study, symptoms decreased and nerve conduction improved.[4]

Shockwave therapy

Shockwaves are directed at the wrist and forearm. According to a meta-analysis, shockwave therapy improved carpal tunnel symptoms, hand function and nerve conduction.[5]

High-intensity magnetic therapy (EMTT)

We use it to ease muscle tension and pain in the forearm and wrist, often together with massage. The procedure is painless and also reaches deeper tissues.

Kinesiotaping

Tape supports wrist position and tissue mobility between sessions. In a meta-analysis, kinesiotaping reduced pain and improved symptoms and hand function.[6]

What the research shows

Non-surgical treatment of carpal tunnel syndrome has been studied extensively. Below is a summary of reviews, meta-analyses and randomised trials that support the methods we use.

Mild and moderate cases are treated without surgery

According to a review in Lancet Neurology, carpal tunnel syndrome is the most common nerve entrapment; mild and moderate cases are first treated non-surgically [1]

Manual therapy matched the results of surgery

In a randomised trial of 120 women, manual therapy reduced pain and improved hand function more than surgery at 1 and 3 months, and at 6 and 12 months the result was as good as after surgery [2]

Massage combined with trigger point therapy

After six weeks of massage and trigger point therapy (twice a week), symptoms and hand function improved significantly – the change was noticeable after just two weeks [3]

Ultrasound reduced symptoms and improved nerve conduction

In a double-blind sham-controlled trial, ultrasound therapy reduced symptoms and improved nerve conduction more than sham treatment; the result was maintained at 6 months [4]

Shockwave improved symptoms and function

In a meta-analysis of randomised trials, shockwave therapy improved carpal tunnel symptoms, hand function and nerve conduction measures [5]

Kinesiotaping reduced pain

In a meta-analysis of 14 randomised trials (637 participants), kinesiotaping reduced pain over the long term in mild to moderate carpal tunnel syndrome and improved symptoms and hand function [6]

Shoulder and neck muscles are involved

In a study of 160 patients, trapezius trigger points were found in all hands with a normal nerve study and in 70% of hands with confirmed carpal tunnel syndrome. That is why we always assess and treat the shoulder and neck area as well [7]

How the course of treatment works

1. 1. Assessment and tests

A conversation about your symptoms and workload, wrist tests, assessment of muscles and mobility, and a check of the nerve pathway from the neck to the fingers. If needed, we recommend seeing a doctor for a nerve conduction study.

2. 2. Reducing tension and pressure

Trigger point therapy, massage and, where appropriate, ultrasound, shockwave or magnetic therapy. During the active treatment phase it is recommended to return within 4–7 days.

3. 3. Restoring mobility

Mobilisation of the wrist, elbow and neck, techniques that improve nerve gliding, kinesiotaping and advice on work posture and wrist position.

4. 4. Maintenance

After the active phase, regular maintenance sessions help keep the result and prevent flare-ups; appointments can be arranged as needed.

What you can do yourself

  • Keep your wrist in a neutral position at the computer – neither bent nor extended upwards. Mouse and keyboard at elbow height.
  • Take breaks from computer and manual work every 30–45 minutes: relax your hand, shake it gently and change position.
  • Avoid sleeping with your wrist curled into a fist or your hands under your head. A night wrist splint in a neutral position may ease night-time symptoms.
  • Use tools with thicker handles and avoid long periods of strong gripping.
  • Alternate the hand you hold your phone in and use voice commands where possible.
  • Seek help early – the shorter the symptoms have lasted, the faster they ease.

Book a hand and wrist assessment

Book an assessment at Viimsi Hospital (Ravi tee 4) or in Pärnu (Rüütli 47). We will find out which muscles and which points along the nerve pathway are involved and agree on a suitable treatment plan.

Frequently asked questions

Yes. Working on the forearm, shoulder and neck muscles together with trigger point therapy has reduced symptoms and improved hand function in studies. Where needed, we also use manual therapy, ultrasound, shockwave and taping.
No. Mild and moderate carpal tunnel syndrome is usually treated without surgery first. In a study, the result of manual therapy for pain and function over a year was as good as surgery. For severe and persistent symptoms we refer you to a doctor.
The median nerve runs from the neck through the shoulder and forearm to the wrist. Tension in the scalenes, pectoralis minor and forearm muscles can cause the same tingling and aggravate wrist symptoms. Treating the whole pathway gives a better result.
It depends on how long the symptoms have lasted and on your workload. We assess the situation at the start of each session. During the active treatment phase sessions are 4–7 days apart, after which you can move to maintenance if needed.
No, no referral is needed. It is worth seeing a doctor with constant numbness, wasting of the thumb muscles or rapidly increasing weakness – if needed, we recommend seeing a doctor, who can refer you for a nerve conduction study.
