Main
- The median nerve is compressed in the narrow carpal tunnel between the bones and the ligament, causing numbness and weakness of the fingers.
- Night-time awakenings due to numbness of the hand are a clear reason to make an appointment with a neurologist or an orthopaedic traumatologist.
- Electroneuromyography shows the speed of signal conduction along the nerve and clarifies the degree of compression.
- Programmers, cashiers, hairdressers and seamstresses encounter this more often because of repetitive movements of the hand.
- Breaks every hour of work, an ergonomic mouse and hand exercises reduce the load on the carpal tunnel.
What is carpal tunnel syndrome
Carpal tunnel syndrome is a condition in which the median nerve is compressed in a narrow canal in the palm. This causes pain, numbness and weakness in the fingers and hand.
What happens in the body
The median nerve passes through the carpal tunnel — a narrow passage between the bones and a dense ligament on the palmar side. In this canal, next to the nerve, are tendons that are responsible for finger movement. When the tissues around the tendons swell or thicken, there is less free space. The pressure on the nerve increases, and it stops conducting signals from the hand to the brain normally. A person begins to notice tingling, burning or a feeling as if the hand has gone numb and will not obey. Over time, weakness is added to this: it becomes difficult to hold small objects, fasten buttons, or hold a spoon steadily. If the cause is not identified in time, the sensitivity and strength of the hand can decrease more and more noticeably, so it is important not to postpone a visit to the doctor.
What causes it to develop
- Prolonged work at a computer: the hand remains in a tense position for a long time, and the pressure in the canal gradually increases.
- Repetitive hand movements: monotonous movements again and again load the same tendons, causing them to swell.
- Wrist injury: a bruise, fracture or sprain changes the lumen of the canal, and the nerve has less room.
- Pregnancy: tissue swelling during this period narrows the canal and creates additional pressure on the nerve.
- Thyroid disease: when its function is impaired, tissues retain fluid, which also compresses the nerve.
- Diabetes mellitus: elevated sugar levels damage nerve fibres, making them more vulnerable to compression.
Who experiences this more often
Carpal tunnel syndrome is more common in people whose work involves constant strain on the hand. These are programmers, cashiers, hairdressers, seamstresses, musicians and everyone who performs the same type of hand movements for long periods. The condition is noted more often in women than in men, which is associated with the structural features of the carpal tunnel and hormonal changes. Pregnancy and the postpartum period also increase the likelihood of unpleasant sensations in the hand. In people with diabetes mellitus or thyroid disorders, the nerve suffers more easily and earlier, so complaints arise even with little strain. Age also matters: over the years, tissues lose elasticity, and the canal tolerates pressure less well. If you notice that your hand goes numb at night or weakens during usual work, it is worth seeing a doctor and not waiting until the condition becomes permanent.
What symptoms can there be?
Carpal tunnel syndrome develops gradually, and the first changes are easily put down to tiredness after working at a computer. The nature and timing of the unpleasant sensations in the hand help you understand what is happening.
How it is noticed at the very beginning
Carpal tunnel syndrome usually starts with a slight tingling in the fingers, which appears after prolonged repetitive strain on the hand. A person notices that the fingers seem to go numb, but as soon as they move the hand, the unpleasant sensation passes. Because of this, the first signs are often explained away by an awkward position or ordinary overwork and are not taken seriously. Gradually the tingling becomes more distinct and involves more and more fingers, and along with it a dull pain appears in the hand. At night or towards morning the numbness wakes the person, and they have to rub the hand to restore sensation. Over time the grip weakens, and it becomes harder to hold everyday objects such as a cup or keys. If such sensations recur regularly, it is worth seeing a neurologist or an orthopaedic traumatologist before they start interfering with work.
Signs that occur most often
- Numbness and tingling in the fingers: sensation is impaired in several fingers, and this is the first sign that is usually noticed.
- Pain in the hand and forearm: the unpleasant sensations spread above the wrist and intensify with strain on the hand.
- Weakness when gripping objects: the hand holds small items less well, so everyday actions take more effort.
- A feeling of "pins and needles" in the fingers: the tingling appears for no reason and quickly passes, but over time it returns more and more often.
- Waking at night because of numbness: the unpleasant sensations in the hand interrupt sleep, and this is a clear reason to visit a doctor.
When to seek urgent help
Examinations and tests
Examination for carpal tunnel syndrome begins with a conversation and a physical examination, and additional methods only clarify the picture. Below is a breakdown of what exactly is prescribed, what each test shows, and which documents are worth bringing to the appointment.
How the examination begins
Carpal tunnel syndrome is recognised primarily by complaints and examination of the hand, not by scans. The doctor asks when and in which fingers the unpleasant sensations appear, and how they change over the course of a day. Then they tap and press on the wrist area, check sensation in the fingers and the strength of the hand muscles. Such sensory tests show whether the median nerve conducts the signal through the tunnel without interference. The doctor compares the affected and healthy hand to notice the difference in sensation and muscle strength. If the picture is unclear or the degree of nerve compression needs to be assessed, additional tests are prescribed. Write down in advance when the symptoms started and what makes them worse — this will noticeably speed up the discussion at the appointment.
What is prescribed and what it shows
What is worth preparing for the appointment
- Discharge summaries: bring all previous doctors' reports so that the specialist can see how the complaints developed and what has already been checked.
- Test results: attach the scans and reports if they were done earlier, this will save you from repeat procedures.
- Symptom diary: note at what time of day and after what kind of strain the unpleasant sensations in the hand appear.
- List of questions: write down in advance what you want to clarify with the doctor so that you do not forget anything during the conversation.
- Information about your work: tell the doctor whether your activity involves prolonged strain on the hands and repetitive movements.
Which doctor should I see?
In carpal tunnel syndrome, care is provided by a neurologist and an orthopaedic traumatologist, and treatment is selected according to the severity of symptoms and the cause of nerve compression. Below — who to book an appointment with, what happens at the initial consultation, and what areas of care make up the treatment.
Which specialist manages this condition
Carpal tunnel syndrome is managed by a neurologist, and if necessary an orthopaedic traumatologist is brought in for observation. The neurologist assesses how the median nerve is functioning and checks the sensitivity of the fingers during the appointment. The orthopaedic traumatologist examines the condition of the hand, tendons and ligaments that may be compressing the nerve. If there is no specialist nearby, start with a general practitioner: they will examine the hand and refer you to the right specialist. At the first appointment, the doctor asks when the numbness and pain appeared and what makes the discomfort worse. Then they check the strength of the hand muscles, sensitivity and mobility of the fingers, comparing both hands. Next, the doctor decides whether conservative care is sufficient or whether surgery should be discussed, and explains the next steps.
What the treatment consists of
- Selection of therapy by the doctor: the specialist determines which methods suit you specifically and changes them as the numbness subsides.
- Physiotherapy: the procedures help relieve swelling around the nerve and restore mobility to the fingers; they are prescribed as a separate area of care.
- Changing the load on the hand: it is important to review work movements so that pressure on the nerve does not return after the condition improves.
- Surgery when indicated: surgical intervention is discussed when conservative methods have not produced the desired effect and symptoms persist.
What depends on the patient themselves
The result of care for carpal tunnel syndrome largely depends on how regularly the person follows the doctor's prescriptions. If physiotherapy is interrupted or one returns to the previous load on the hand, numbness and pain may return. Observation by a neurologist or orthopaedic traumatologist allows one to notice in time that the chosen direction is not working. It is worth honestly telling the doctor which movements at work or at home make the discomfort in the fingers worse. Then the specialist will adjust the care and decide whether the approach to treatment needs to be changed. A patient who comes to the appointment at the appointed time helps the doctor see the dynamics rather than a one-off picture. An open conversation about what prevents following the recommendations often changes the tactics for the better. Book a follow-up appointment if the symptoms do not ease or return after improvement.
What helps prevent an exacerbation?
Carpal tunnel syndrome prevention is based on reducing the load on the wrist and proper ergonomics of the workplace. Regular breaks and hand exercises reduce the risk of flare-ups.
What to change in your habits
Daily habits when working at a computer directly affect the load on the wrist and the course of the condition. Holding the hand in one position for a long time without support creates constant tension in the carpal tunnel area. The habit of taking short breaks every hour of work allows the muscles and tendons to recover. An ergonomic mouse and keyboard keep the hand in a neutral position and reduce pressure on the median nerve. Hand exercises — flexion, extension, rotation — improve blood flow and joint mobility. If these habits are ignored, tension accumulates by the end of the day and manifests as heaviness and numbness in the fingers. It is worth restructuring the working day so that breaks and warm-ups become a regular part, not a rare exception.
What to keep under control
- Breaks when working at a computer: short pauses during the day reduce the accumulation of tension in the wrist and prevent fatigue from developing into persistent discomfort.
- Workplace ergonomics: the position of the mouse, keyboard and the height of the desk affect the angle of the hand, and therefore the pressure inside the carpal tunnel.
- Hand exercises: regular warm-ups maintain joint mobility and blood flow, so it is better to do them throughout the day rather than occasionally.
- Prolonged wrist tension: the habit of holding the hand unsupported for long periods increases the load, and this is worth noticing and changing position in time.
- Your own sensations: heaviness, tingling or numbness in the fingers by the end of the day serve as a signal to review the load and discuss it with a doctor.
How often to see a doctor
Regular check-ups with a doctor are needed even when the wrist does not bother you and you feel well. The specialist assesses hand mobility and compares the condition with the previous examination, noticing changes earlier than the person themselves. Familiar movements can mask a gradual deterioration that only manifests during a targeted check. The doctor will advise how to adjust ergonomics and load taking into account your specific work and lifestyle. If heaviness, tingling or numbness in the fingers appear, the visit should not be postponed. Scheduled check-ups help to notice in time that the usual measures have stopped helping and to review the approach. It is reasonable to agree with the doctor on a convenient rhythm for such visits and to keep to it consistently.
What is worth remembering
Carpal tunnel syndrome develops gradually, and its early signs are easily mistaken for ordinary tiredness after working at a computer. Understanding what is happening to the hand matters before the unpleasant sensations become permanent.
Key takeaways
Carpal tunnel syndrome is a condition in which compression of a nerve in the narrow carpal tunnel makes itself felt through numbness, tingling and weakness of the fingers. This is most noticeable at night or after prolonged repetitive strain on the hands. Over time, reduced sensation and clumsiness with fine movements are added to the unpleasant sensations. Carpal tunnel syndrome does not go away on its own if the cause of the compression persists. The earlier a person pays attention to recurring symptoms, the easier it is to choose a suitable approach. Many postpone a visit to the doctor, putting the discomfort down to tiredness or an awkward sleeping position. Carpal tunnel syndrome requires not patience, but a timely conversation with a specialist. The foundation for solving it is not a search for ready-made advice, but an honest assessment of how often and how severely the hand is troubling you.
