Written by Carpal Tunnel Syndrome: Tingling Fingers and Night-Time Numbness
You wake in the night with your hand tingling or numb, and find yourself shaking it to get the feeling back. Or you drop your keys, struggle with buttons, or notice pins and needles when you hold a phone, a book or the steering wheel. These are classic signs of carpal tunnel syndrome, a very common hand problem.
Carpal tunnel syndrome can often be helped with simple things you can do yourself, though it can take a few months to settle. This guide explains what it is, what tends to cause it, what usually helps, and when to see a doctor. It can't tell you what is causing your own symptoms, but it can help you know where to start.
What carpal tunnel syndrome is and how it feels
On the palm side of your wrist there's a narrow passage called the carpal tunnel. It's formed by the small bones of your wrist and a tough band of tissue across the top. Through this tunnel run the tendons that bend your fingers and an important nerve called the median nerve.
The median nerve gives feeling to your thumb, index finger, middle finger and half of your ring finger. It also powers some of the muscles at the base of your thumb. Carpal tunnel syndrome happens when the tissues in the tunnel swell and squeeze this nerve.
It can feel like:
- tingling or pins and needles in the thumb and first fingers
- numbness in those fingers, often waking you at night
- an ache or pain in the fingers, hand, wrist or up the arm
- a weak grip, or a thumb that feels clumsy, so you drop things
- trouble with fiddly jobs like buttons, jewellery clasps or opening jars
Symptoms usually start slowly and come and go. They're often worse at night or first thing in the morning, and when you hold your wrist bent for a long time, for example while reading, knitting, driving or using a phone. Many people find that shaking or hanging the hand eases it for a while. It can affect one or both hands.
Common causes
Often there's no single cause. Things that make carpal tunnel syndrome more likely include:
- work or hobbies that mean you bend your wrist a lot or grip hard for long periods, such as using vibrating tools, gardening, knitting or playing an instrument
- carrying extra body weight
- pregnancy, when fluid can build up in the tissues
- other conditions such as diabetes, rheumatoid arthritis, osteoarthritis of the wrist or an underactive thyroid
- an old wrist injury or break
- a family history of carpal tunnel syndrome
- getting older, and it's more common in women than men
What usually helps
Wear a wrist splint at night. A splint keeps your wrist straight while you sleep, which takes pressure off the nerve. Many people find this is one of the most helpful things they can do. You can buy splints from pharmacies or online. It may take up to 6 weeks of wearing one at night to feel the full benefit.
Cut down on what sets it off. Notice which activities bring on your symptoms, then take more breaks, switch hands, or do them a different way. Try to avoid long spells of gripping hard or bending your wrist, and give vibrating tools a rest where you can.
Keep your wrist straight during the day. When typing, reading, sewing or using a phone, try to keep your wrist level rather than bent up or down. Resting a book on a cushion or using a phone holder can help.
Try gentle hand exercises. There's some evidence that simple hand and finger exercises can ease symptoms. A physiotherapist or hand therapist can show you which ones suit you.
Loosen your grip. Use pens and utensils with thicker, padded handles, and don't grip harder than you need to. Jar openers and kitchen gadgets can save your hands a lot of strain.
Ask about pain relief. Pain relief may help for a short time, but it doesn't treat the cause, so it's best not to rely on it. A pharmacist can tell you what's suitable for you.
Know the other options. If self-care isn't enough, a doctor may suggest an injection into the wrist to reduce swelling, or a short operation to make more room for the nerve. The operation is usually done while you're awake with your wrist numbed, and you go home the same day.
What to try this week
When to see a doctor
Call 911 (or your local emergency number) if:
- you suddenly have numbness or weakness in your face, arm or leg, especially on one side, or trouble speaking or seeing (these can be signs of a stroke)
- you have arm or hand pain with chest pain, sweating or shortness of breath
Call your doctor the same day, or get urgent care, if:
- your hand or wrist symptoms started after a fall or injury, or your wrist looks deformed or badly swollen
- your hand or fingers are cold, pale or blue
- you suddenly can't feel your fingers or move your thumb
Book an appointment within 1 to 2 weeks if:
- your symptoms are getting worse or not going away
- treatment at home, like a splint, isn't helping after a few weeks
- numbness is there all the time, not just at night
- your thumb feels weak, you keep dropping things, or the muscle at the base of your thumb looks thinner
- you have tingling in both hands along with symptoms elsewhere, such as your feet
Constant numbness or thumb weakness are worth checking soon, because long-term pressure can damage the nerve. If you take medicines, don't change or stop them without talking to your doctor or pharmacist first.
Common questions
Does typing cause carpal tunnel syndrome?
Typing hasn't been clearly shown to cause it, but it can make symptoms worse for people who already have it. Keeping your wrists straight and taking regular breaks helps.
Will it go away on its own?
Sometimes, yes, especially if it's linked to pregnancy, or to an activity you can change. For many people, a night splint and small changes to how they use their hands are enough. Others need further treatment.
How do I know it's carpal tunnel and not something else?
Tingling in the thumb and first fingers, worse at night, is typical. But numbness in the hands can have other causes, such as a trapped nerve in the neck or nerve damage from diabetes. A doctor can usually tell from your symptoms and a quick hand examination, and may arrange nerve tests if unsure.
Is surgery a big operation?
It's usually a short operation, often about 20 minutes, done with your wrist numbed, and you go home the same day. It can take around a month to get back to normal activities. It's usually only suggested if other treatments haven't worked or symptoms are severe.
Should I wear my splint during the day too?
Most people only need it at night. Wearing it all day can make the wrist stiff. Ask a doctor or hand therapist if you think you need it in the day as well.
