What does carpal tunnel syndrome feel like?

Tingling, numbness or pins and needles in the thumb, index and middle fingers, sometimes with aching in the hand or forearm. Symptoms are typically worse at night and may wake you; shaking the hand often relieves them.

Pressure on the median nerve as it passes through the carpal tunnel in the wrist. It is more common in pregnancy, with repetitive hand work, in people with diabetes or thyroid problems, and often has no single clear cause.

How is carpal tunnel syndrome treated?

Mild cases often improve with a wrist splint worn at night and adjusting aggravating activities. Steroid injections help some people. For persistent or severe cases, a small operation to release the pressure is very effective.

Will it go away on its own?

Sometimes — especially when linked to pregnancy or a temporary activity. But persistent symptoms tend to continue or worsen without treatment, and long-standing pressure can damage the nerve, so don't ignore ongoing symptoms.

Quick answer

What is carpal tunnel syndrome?

Carpal tunnel syndrome is caused by pressure on a nerve in the wrist. It causes tingling, numbness and sometimes pain in the hand and fingers, often worse at night. Mild cases often improve with a wrist splint and adjusting activities; persistent cases have effective treatments, including a small operation.

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 — comes under pressure. The result is tingling, numbness and discomfort in the hand. It is common, often worse at night, and very treatable.

Symptoms

Typical symptoms include:

tingling, numbness or pins and needles in the thumb and first two or three fingers
aching or discomfort in the hand, wrist or forearm
symptoms that wake you at night, often relieved by shaking the hand
in longer-standing cases, weakness of grip or thumb muscles

What causes it

Anything that narrows the tunnel or swells its contents can press on the nerve. It is more common during pregnancy, with repetitive gripping or wrist work, and in people with conditions such as diabetes or an underactive thyroid — though often no single cause is found.

Treatment

For mild or recent symptoms, a wrist splint worn at night (keeping the wrist straight) helps many people, alongside adjusting activities that aggravate it. Steroid injections can settle symptoms for some. Where symptoms persist or are severe, a small operation to release the ligament over the tunnel is highly effective and usually done as a day case.

When to see a GP

See a GP if symptoms persist, disturb sleep, or affect daily tasks — and sooner if you notice constant numbness, weakness, or wasting of the muscle at the base of the thumb, since the nerve recovers best when treated before permanent changes set in.
