Waking up with pins and needles in your fingers, or shaking your hand out to get the feeling back, is a common experience for people with carpal tunnel syndrome. It often starts as a mild nuisance at night and can gradually creep into the day, making it harder to type, hold a phone or grip a steering wheel.
The good news is that many people with mild to moderate symptoms improve with simple, conservative care. Knowing what is going on, what tends to make it worse and when to get it checked can make a real difference to how quickly you get back to normal tasks.
What is carpal tunnel syndrome?
The carpal tunnel is a narrow passage on the palm side of your wrist, formed by the small wrist bones and a tough band of tissue called the transverse carpal ligament. Nine tendons that bend your fingers pass through it, along with the median nerve.
Carpal tunnel syndrome happens when pressure inside this tunnel increases and irritates the median nerve. Because the median nerve supplies sensation to the thumb, index, middle and part of the ring finger, symptoms usually show up in those fingers rather than the little finger.
What are the common symptoms?
Symptoms tend to come and go at first, then can become more constant if the nerve stays under pressure for a long time. Common signs include:
Tingling, numbness or burning in the thumb, index and middle fingers
Symptoms that wake you at night or are worse first thing in the morning
A need to shake or flick your hand to ease the tingling
Clumsiness, dropping things or trouble with fine tasks like doing up buttons
Aching that can spread into the forearm
In longer standing cases, weakness or thinning of the muscles at the base of the thumb
What causes it, and who is more likely to get it?
Often a combination of factors adds up. Repetitive or forceful gripping, prolonged wrist bending, and using vibrating tools can all contribute. Fluid retention also plays a part, which is why carpal tunnel symptoms are common during pregnancy and often settle after the baby arrives.
Health conditions such as diabetes, an underactive thyroid, rheumatoid arthritis and a previous wrist fracture are linked with a higher risk. It is also more common in women and in people over 40. If you work at a desk, your setup may not be the root cause, but small changes to your posture and workstation can reduce the load on your wrists.
How is carpal tunnel syndrome diagnosed?
A diagnosis is usually based on your symptoms and a hands-on assessment. Your practitioner will ask about the pattern of your symptoms, check sensation and strength in your hand, and may use simple tests such as tapping over the nerve or holding the wrist in a bent position to see if symptoms are reproduced.
It is also important to rule out other sources of hand tingling. A pinched nerve in the neck, nerve irritation at the elbow and some medical conditions can feel similar. If the picture is unclear or symptoms are severe, your GP may arrange nerve conduction studies, which measure how well the median nerve is working. You can read more about related symptoms on our arm pain, numbness and tingling page.
When should you see a physio?
It is worth booking an assessment if your symptoms are lasting more than a couple of weeks, keep returning, or are starting to affect your sleep or work. Conservative care tends to work better before the nerve has been compressed for a long time.
You may want to see a physio sooner if you notice:
Tingling that wakes you most nights
Symptoms during the day that interrupt typing, driving or gripping
Any weakness, clumsiness or dropping objects
Symptoms during pregnancy that are making daily life hard
Tingling that also involves your neck, shoulder or the whole arm
What might treatment involve?
A physiotherapist may suggest a wrist splint worn at night to keep the wrist in a neutral position, which research suggests can help ease night symptoms for many people. Advice on modifying aggravating tasks, taking regular breaks and adjusting grip is also a key part of care.
Other approaches may include nerve and tendon gliding exercises, hand and forearm strengthening once symptoms settle, and treatment of the neck or upper limb if those areas are contributing. For some people, a GP may discuss a corticosteroid injection, which can provide short term relief. If symptoms are severe, constant or there is muscle wasting, a referral for a surgical opinion may be appropriate. Our carpal tunnel syndrome treatment page explains more about how we approach care.
When should you see a GP or seek urgent care?
Most carpal tunnel symptoms are not an emergency, but some signs need prompt medical review. See your GP if numbness is constant, if you notice wasting of the muscles at the base of your thumb, or if symptoms affect both hands along with other changes such as unexplained weight gain, fatigue or feeling unusually cold.
Seek urgent care if hand numbness or weakness comes on suddenly, especially with facial drooping, slurred speech or weakness on one side of the body, as these can be signs of a stroke. Rapid swelling and severe pain after a wrist injury also needs urgent assessment to rule out a fracture.
Frequently asked questions
Can carpal tunnel syndrome go away on its own?
Mild cases, particularly those linked to pregnancy or a short period of heavy hand use, can settle with time and simple changes. Symptoms that persist or worsen are worth having assessed, as early care may help reduce the risk of ongoing nerve irritation.
Is carpal tunnel the same as a pinched nerve in the neck?
No, although they can feel similar and sometimes occur together. A pinched nerve in the neck often comes with neck pain and symptoms in a different pattern down the arm. An assessment can help work out where the irritation is coming from.
Do I need a referral to see a physio?
No referral is needed for most appointments at our clinic. If you have a chronic condition, your GP may be able to set up a Medicare Chronic Condition Management plan, which provides a rebate for a limited number of allied health visits each calendar year. Check with your GP about eligibility.
