The symptoms of carpal tunnel syndrome include:

• an ache or pain in your fingers, hand or arm
• numb hands
• tingling or pins and needles
• a weak thumb or difficulty gripping

These symptoms often start slowly and come and go. They're usually worse at night.

Carpal tunnel syndrome (CTS) sometimes gets better by itself in a few months, particularly if you have it because you're pregnant.

Wear a wrist splint

A wrist splint is something you wear on your hand to keep your wrist straight. It helps to relieve pressure on the nerve.

You wear it at night while you sleep. You may need to wear a splint for up to 6 weeks before it starts to feel better.

You can buy wrist splints online or from pharmacies.

Stop or cut down on things that may be causing it

Stop or cut down on anything that causes you to frequently bend your wrist or grip hard, such as using vibrating tools for work or playing an instrument.

Painkillers

Painkillers like paracetamol or ibuprofen may help carpal tunnel pain short-term.

But there's little evidence to say they can treat the cause of CTS, so it's important not to rely on them.

Hand exercises

There's a small amount of evidence to suggest hand exercises help ease the symptoms of CTS.

The Chartered Society of Physiotherapy has instructions for simple hand exercises you can try.

See a GP if:

Carpal tunnel syndrome (CTS) can usually be diagnosed by asking about your symptoms and checking your hand.

If the health professional is not sure it's CTS, they may refer you to hospital for:

• a test of the nerves in your wrist (nerve conduction test)
• scans such as an ultrasound scan or MRI scan

If you have carpal tunnel syndrome (CTS) and a wrist splint does not help, a steroid injection into your wrist might be recommended. This brings down swelling around the nerve, easing the symptoms of CTS.

Steroid injections are not always a cure. CTS can come back after a few months and you may need another injection.

If your CTS is getting worse and other treatments have not worked, you might be referred to a specialist to discuss surgery.

Surgery usually cures CTS. You and your specialist will decide together if it's the right treatment for you.

An injection numbs your wrist so you do not feel pain (local anaesthetic) and a small cut is made in your hand. The carpal tunnel inside your wrist is cut so it no longer puts pressure on the nerve.

The operation takes around 20 minutes and you do not have to stay in hospital overnight.

It can take a month after the operation to get back to normal activities.

Carpal tunnel syndrome (CTS) happens when the carpal tunnel inside your wrist swells and squeezes 1 of your nerves (median nerve).

You're more at risk of CTS if you:

• are overweight
• are pregnant
• do work or hobbies that mean you repeatedly bend your wrist or grip hard, such as using vibrating tools
• have certain other conditions, such as arthritis or diabetes
• have a parent, brother or sister with CTS
• have previously injured your wrist
