Carpal tunnel syndrome happens when the median nerve, which runs through a narrow passage in the wrist called the carpal tunnel, becomes compressed, causing numbness, tingling, and pain in the hand and fingers, particularly the thumb, index, and middle fingers. It's often worse at night and can be triggered or worsened by repetitive hand movements, pregnancy, or certain underlying conditions.

What is Carpal Tunnel Syndrome?
Carpal tunnel syndrome happens when the median nerve, which runs through a narrow passage in the wrist called the carpal tunnel, becomes compressed, causing numbness, tingling, and pain in the hand and fingers, particularly the thumb, index, and middle fingers. It's often worse at night and can be triggered or worsened by repetitive hand movements, pregnancy, or certain underlying conditions.
Mild cases often improve with simple measures like wrist splints and activity changes, while more persistent or severe cases may need further treatment, including injections or, in some cases, surgery to relieve the pressure on the nerve.

Clinical context
Night-time symptoms are a classic feature
Many people with carpal tunnel syndrome notice their symptoms are worse at night or upon waking, sometimes needing to shake out the hand for relief — this pattern is a helpful clue in recognising the condition.
03 · Act
When to See a Doctor
- 1Numbness, tingling, or pain in the hand persists or worsens
- 2Symptoms are affecting your grip strength or ability to perform daily tasks
- 3Symptoms don't improve with a wrist splint and activity changes
- 4You notice muscle wasting at the base of the thumb, which can indicate more advanced nerve compression

Practical steps
A Wrist Splint Worn at Night Often Helps Significantly
Wearing a wrist splint that keeps the wrist in a neutral position, particularly at night, is one of the most effective simple measures for easing carpal tunnel symptoms.
- 1Wear a wrist splint, especially at night.This keeps the wrist in a neutral position, reducing pressure on the nerve.
- 2Take breaks from repetitive hand movements.Regular breaks during activities like typing or manual work can reduce strain.
- 3Adjust your workstation ergonomics.Keeping wrists straight while typing or using a mouse can help reduce symptoms.
- 4Try gentle wrist stretches.These can help ease tension, though a physiotherapist can advise on the most suitable exercises.
- 5See a doctor if symptoms persist.Further treatment options, including injections or surgery, are available for more significant cases.
