Hands Going Numb at Night? Carpal Tunnel or Neck — How to Tell Which Side to Look At

Numbness in the hand is often put down to "poor circulation", but in most cases the nerves are under pressure, and where that pressure sits matters. As a general guide, tingling in the thumb, index and middle fingers points toward the wrist (the carpal tunnel), while numbness across the whole hand that runs up the forearm and into the shoulder points toward the neck. limda k-medical clinic (경희림다한의원) is in Haeundae Marine City, Busan, on the ground floor of iPark Tower 1 next to Park Hyatt Busan, and we work out which it is at the consultation. Everything below is a guide, not a diagnosis.

Which fingers tell you where to look

• Thumb, index, middle finger and half of the ring finger: the typical pattern when the median nerve is pressed at the wrist
• Ring finger and little finger: we think first of the inner elbow or the lower neck
• The whole hand, plus a feeling that runs into the forearm or shoulder: more likely a nerve under pressure in the neck

Time of day and posture add another clue

• Waking at dawn with numb hands that ease when you shake them out is a pattern seen with the wrist, because the wrist bends during sleep and the pressure increases
• Numbness that gets worse when you tilt your head back or turn it toward the sore side is a neck signal
• A day of heavy mouse and keyboard use tends to point to the wrist; a day spent looking down at a screen tends to point to the neck
• Neck or shoulder pain alongside the numbness raises the weight we give to the neck

A simple check at home

Press the backs of your hands together in front of your chest, bend both wrists to 90 degrees and hold for one minute. If the numbness comes back, it is a wrist-side signal (the Phalen test). This is only a reference. What is actually behind your symptoms is checked at the consultation at Limda.

How we approach it at Limda

Numbness is often produced by two things together: the structure where the nerve passes and the tension of the muscles around it. For the wrist side, acupuncture to ease the tissue around the wrist tunnel and the forearm fascia is the centre of care. For the neck side, we work on the deep neck and shoulder muscles (scalenes, levator scapulae and others) so that the space around the nerve is under less strain. Which one applies, and how often to come, is decided after the examination.

Seven daily habits for hands that go numb

• Wear a wrist splint at night. Simply keeping the wrist from bending is enough for many people.
• Set your mouse height so the wrist does not bend, and use a wrist rest at the keyboard.
• Every hour, take 30 seconds for a wrist stretch and slow neck rotations, as a pair.
• Bring the top of the monitor to eye level. Every centimetre the head moves forward adds load to the neck.
• Avoid long stretches of holding a phone and typing with one thumb. Mix in voice input.
• If numbness worsens in the cold, keep the wrist and neck warm. A warm compress may help muscles relax.
• If you are pregnant or in menopause, hormones and swelling can play a part, so please ask us at the consultation rather than correcting things on your own.
