Wrist & Hand PainCarpal Tunnel, RSI & Tendinopathy
Carpal tunnel syndrome, repetitive strain, wrist tendinopathy, and hand pain from keyboard and mouse use. The source is often higher up the arm than the symptoms suggest.
Book Your First VisitHand numbness and tingling can come from the wrist, the elbow, or the cervical spine. Getting the source right is essential because the treatment is entirely different for each. Cervical nerve root referral (C6, C7, C8) can produce very similar symptoms to carpal tunnel syndrome and is worth ruling out.
Why hand symptoms often come from higher up
For most desk workers with hand tingling or numbness, carpal tunnel syndrome is the first thing to consider. But hand symptoms can also arise from structures higher up the arm, which is why getting the source right matters. Cervical nerve roots (C6, C7, C8), the brachial plexus (the nerve network that runs from the neck through the shoulder), or the thoracic outlet can all produce hand pain, numbness, and tingling that can be difficult to distinguish from local wrist pathology on symptoms alone, without a clinical assessment. Getting the source right is essential, because the treatment is entirely different.
C6 nerve root referral produces numbness in the thumb, index finger, and lateral forearm (an overlap with median nerve territory that can make these two conditions difficult to distinguish on symptoms alone). C7 referral typically affects the middle finger and posterior forearm. C8 referral affects the little finger and the ulnar side of the ring finger, similar to ulnar nerve symptoms. A thorough neurological assessment, including cervical provocation tests, reflexes, and sensation mapping, is necessary to tell these apart.
Common causes
- Carpal tunnel syndrome: compression of the median nerve at the wrist. Classic pattern: numbness and tingling in the thumb, index, middle, and thumb-side half of the ring finger (median nerve distribution), often worse at night or with sustained wrist flexion. Conservative care is appropriate for mild-to-moderate cases (wrist mobilization, nerve gliding exercises, ergonomic modifications, night splinting).
- Cervical nerve root referral: C6, C7, or C8 nerve root irritation from a cervical disc or joint problem, producing arm and hand symptoms that mimic local wrist pathology. A frequently overlooked cause of hand symptoms in desk workers.
- De Quervain's tenosynovitis: pain on the thumb side of the wrist, aggravated by gripping and thumb movement. Common in new parents and people who use a phone extensively with thumb scrolling.
- Thoracic outlet syndrome: compression of neurovascular structures between the clavicle, first rib, and scalene muscles. Produces diffuse arm, forearm, and hand symptoms, often underdiagnosed because its presentation overlaps with carpal tunnel syndrome and cervical radiculopathy (nerve compression from a disc or joint problem in the neck). It is less common than carpal tunnel syndrome or cervical referral, and usually presents with diffuse rather than finger-specific symptoms.
- Repetitive strain (RSI): an umbrella term for cumulative load injury from sustained repetitive keyboard and mouse use. Usually presents as forearm and wrist fatigue and ache, without the specific neurological pattern of nerve compression.
What helps
Treatment depends entirely on what's driving the symptoms. For carpal tunnel, night splinting and nerve gliding exercises are the best-supported conservative options for mild-to-moderate cases, with wrist joint mobilization adding benefit in some presentations. Moderate-to-severe cases with significant electrodiagnostic findings (nerve conduction studies and EMG) or progressive weakness need surgical consultation.
For cervical nerve root involvement, the treatment targets the cervical spine: manipulation or mobilization of the affected level, cervical traction if appropriate, and nerve mobilization techniques. If the source is in the cervical spine rather than the wrist, treatment focused on the wrist will have limited effect.
Ergonomic changes: worth trying, modest evidence
Mouse position, keyboard angle, and arm support are commonly recommended for wrist and forearm symptoms in desk workers. A Cochrane review of ergonomic interventions found the evidence is inconsistent, with most physical changes showing limited effect on their own. The best reason to adjust your setup is that it costs nothing and has no downside. A mouse placed too far from the body creates sustained shoulder elevation and forearm pronation. A keyboard that forces wrist extension increases carpal tunnel pressure. These are worth correcting regardless.
If you're waiting on nerve conduction study results and want to do something useful in the meantime: a neutral-wrist night splint (available at most pharmacies) can reduce overnight symptoms in carpal tunnel and is unlikely to interfere with your test results. Adjusting your mouse position and keyboard angle costs nothing and is worth doing regardless of how the diagnosis resolves.

When to seek care promptly
See a doctor if you have:
- Progressive weakness in the hand, particularly with gripping or pinching
- Wasting (visible muscle loss) of the muscles at the base of the thumb
- Wrist pain after a fall on an outstretched hand; scaphoid fractures are easily missed
- Hand symptoms alongside neck pain or arm pain with neurological signs
- Sudden onset of hand weakness or numbness without a clear mechanical cause
- Arm or hand swelling, visible vein distension, or colour change in the hand (skin that goes pale, bluish, or blotchy), as these may indicate vascular compression requiring urgent assessment
- Bilateral hand symptoms, difficulty with fine motor tasks (buttoning, dropping things), or a sensation running down the spine when bending the neck forward: these may indicate spinal cord involvement and need urgent assessment
Moderate-to-severe carpal tunnel with significant weakness or nerve conduction changes needs surgical review. I'll tell you if your presentation is one of them.
Common questions
Carpal tunnel syndrome has a recognisable pattern: numbness and tingling in the thumb, index, middle, and thumb-side half of the ring finger. The distribution of the median nerve. Symptoms are often worse at night and when the wrist is sustained in flexion (holding a phone, typing). But similar symptoms can come from median nerve compression higher up the arm, or from cervical radiculopathy at C6. Getting the diagnosis right matters because the treatment is different. A clinical assessment can help clarify whether your presentation fits a straightforward median nerve pattern or whether cervical involvement is worth investigating. It also gives you a clearer set of questions to bring to a specialist appointment. I'll assess the full picture and identify where the compression is actually occurring before we decide on management.
Night-time hand numbness is a common presentation with several possible causes. Carpal tunnel syndrome is the most frequent, sustained wrist flexion during sleep compresses the median nerve in the carpal tunnel. But sleep position also matters: tucking the arms under the body or sleeping with bent elbows can compress the ulnar nerve at the elbow. Cervical spine compression can also produce nocturnal symptoms. I'll assess the distribution of numbness and the positions that provoke it, which usually points clearly to the source.
Not necessarily, and not as a first step. Mild to moderate carpal tunnel syndrome is appropriate to trial conservatively first: wrist splinting at night, activity modification, nerve gliding exercises, and treatment of any contributing factors (wrist or mid-back restriction, ergonomic issues). A corticosteroid injection, usually administered by a GP or specialist, is another option if conservative (non-surgical) care hasn't provided enough relief before surgery is considered. Surgery is appropriate when conservative care has genuinely failed, when there is visible muscle wasting at the base of the thumb (the thenar eminence), or when electrodiagnostic studies (nerve conduction studies and EMG) show severe compression. I'll give you an honest assessment of where your presentation sits and whether a conservative trial is worth pursuing first.
Nerve gliding (or neural mobilisation) exercises move the nerve through its surrounding tissue, improving its ability to slide freely through the carpal tunnel and along its full course. The evidence for nerve gliding in carpal tunnel syndrome is moderately positive2,3; it is typically used alongside splinting rather than as a replacement for it. Studies show improvement with both approaches, though the additional benefit of nerve gliding over splinting alone is not firmly established. The exercises need to be done correctly: too aggressive and they can irritate the nerve further. I'll show you the appropriate technique and frequency based on your presentation.
Yes, cervical radiculopathy at C6, C7, or C8 can produce pain, numbness, or tingling that radiates into the forearm and hand in a pattern that overlaps with carpal tunnel syndrome. The distinction matters because treating the wrist won't resolve nerve compression in the neck. Clues that the neck is involved: symptoms that extend above the wrist, associated neck pain or stiffness, and symptoms that are reproduced by neck movements. I'll assess both the cervical spine and the peripheral pathway to identify where the problem is actually originating.
