Pins and Needles in Hands at Night: Common Causes

Waking with pins and needles in one or both hands is common. It often happens because you have slept with your wrist bent or put pressure on an arm, temporarily affecting a nerve or its blood supply.

If the sensation disappears quickly after changing position, it is usually not serious. Repeated night-time tingling, numb fingers, hand weakness or symptoms that continue during the day may indicate a compressed or damaged nerve.

The location of the tingling provides useful clues:

Area affected	Possible explanation
Thumb, index and middle fingers	Carpal tunnel syndrome affecting the median nerve
Little finger and half of the ring finger	Pressure on the ulnar nerve, commonly at the elbow
Hand and arm with neck or shoulder pain	A nerve irritated in the neck
Both hands and possibly both feet	Peripheral neuropathy or a medical cause such as diabetes
Cold fingers that change colour	Raynaud’s phenomenon or another circulation problem
Sudden numbness with facial or arm weakness	Possible stroke or transient ischaemic attack

Call 999 immediately if numbness starts suddenly with facial drooping, weakness on one side, difficulty speaking, confusion, loss of balance or a severe new headache. These can be symptoms of a stroke, even if they improve quickly.

This guide provides general information. Tingling cannot be diagnosed reliably from its location alone, particularly when several nerves or medical conditions could be involved.

Why do hands develop pins and needles at night?

Pins and needles, medically called paraesthesia, occurs when sensory nerves send abnormal signals to the brain. It may feel like tingling, prickling, buzzing, burning or tiny electric shocks.

During sleep, you may keep the same position for a long time without noticing pressure or discomfort. Common examples include:

sleeping with a hand underneath your head or pillow;
lying directly on an arm;
keeping the wrist tightly bent;
sleeping with the elbow deeply flexed;
resting the inner elbow against a hard surface;
allowing the arm to hang awkwardly over the edge of the bed.

This can compress a nerve, reduce its blood supply or do both. When you change position, normal nerve function returns and the hand may tingle intensely for a short time before recovering.

Occasional positional tingling usually settles within a few minutes. Symptoms that wake you frequently, consistently affect particular fingers or leave lasting numbness need closer attention.

See the NHS overview of pins and needles and when to contact a GP.

Is carpal tunnel syndrome the most likely cause?

Carpal tunnel syndrome is one of the most common causes of recurrent hand tingling at night. It happens when the median nerve is compressed as it passes through a narrow space at the wrist.

The median nerve normally supplies sensation to the:

thumb;
index finger;
middle finger;
thumb-side half of the ring finger.

The little finger is usually unaffected. However, symptoms do not always follow a perfect textbook pattern, and some people describe their whole hand as numb.

Typical carpal tunnel symptoms include:

pins and needles in the thumb and nearby fingers;
numbness that wakes you during the night;
a need to shake or hang the hand out of bed;
burning or aching in the hand and forearm;
symptoms when driving, holding a phone or reading;
reduced grip strength;
dropping cups or other objects;
difficulty fastening buttons or handling small items.

Night-time symptoms are common because people naturally sleep with their wrists bent. Fluid distribution in the body may also contribute to pressure within the tunnel.

Carpal tunnel syndrome is more likely during pregnancy and in people with diabetes, rheumatoid arthritis, an underactive thyroid or a previous wrist injury. Sometimes no clear underlying cause is found.

Our complete guide to carpal tunnel syndrome symptoms and treatment explains the condition in more detail. You can also read the official NHS carpal tunnel guidance.

Could the ulnar nerve be trapped at the elbow?

If tingling mainly affects the little finger and adjacent half of the ring finger, pressure on the ulnar nerve is a possible explanation.

This nerve passes through a vulnerable area on the inside of the elbow, often called the funny bone. Keeping the elbow bent for a long period can stretch and compress it. Sleeping with the arms folded tightly or with a hand tucked beneath the face may trigger symptoms.

Possible signs of ulnar nerve compression include:

tingling or numbness in the little and ring fingers;
symptoms that worsen when the elbow is bent;
aching along the inner forearm;
weakness when spreading the fingers;
difficulty gripping or manipulating small objects;
loss of hand-muscle bulk in advanced cases.

The nerve may be compressed at the elbow, known as cubital tunnel syndrome, or less commonly at the wrist.

Try not to sleep with the elbow tightly bent. Some people find that loosely wrapping a folded towel around the elbow discourages extreme bending. It should never be tight enough to restrict circulation.

Can a neck problem cause tingling in the hands?

Nerves travelling to the hands begin in the neck. A nerve root can become irritated by age-related spinal changes, inflammation or a slipped disc. This is sometimes called cervical radiculopathy.

Symptoms may include:

neck or shoulder-blade pain;
pain travelling down one arm;
tingling in part of the hand;
numbness in the arm or fingers;
arm or hand weakness;
symptoms affected by neck position.

Different nerve roots supply different regions, but the patterns overlap. A clinician will consider the combination of pain, sensation, reflexes and muscle strength rather than diagnosing the problem from one finger alone.

Seek prompt medical assessment if neck pain is accompanied by worsening weakness, clumsy hands, difficulty walking, loss of balance, altered bladder or bowel control, or numbness around the genitals or bottom. These may indicate significant pressure on the spinal cord or nerves.

What medical conditions can cause night-time tingling?

Not every case begins in the wrist, elbow or neck. Conditions affecting nerves throughout the body can also cause tingling, although the feet are often affected before the hands.

Diabetes

Persistently high blood glucose can damage peripheral nerves. Diabetic peripheral neuropathy commonly produces numbness, tingling, burning or pain in the feet and may later affect the hands.

Diabetes is more plausible when tingling occurs alongside symptoms such as increased thirst, frequent urination, unexplained weight loss, tiredness, blurred vision or slow-healing wounds. Many people with type 2 diabetes initially have few obvious symptoms.

Read our guides to early signs of type 2 diabetes and when diabetes screening may be appropriate.

Vitamin B12 deficiency

Vitamin B12 is important for healthy nerves and blood cells. Deficiency can cause pins and needles, numbness, weakness, tiredness, balance problems, memory changes and a sore or red tongue.

Possible causes include pernicious anaemia, conditions affecting the stomach or bowel, some medicines and a diet containing insufficient vitamin B12.

Nerve damage can become permanent if a significant deficiency is left untreated. Do not start high-dose supplements as a substitute for assessment if you have neurological symptoms; identifying and treating the cause matters.

See the NHS guide to vitamin B12 or folate deficiency symptoms.

Underactive thyroid

Hypothyroidism can contribute to fluid retention and nerve compression, including carpal tunnel syndrome. Other possible symptoms include tiredness, feeling cold, constipation, weight gain, dry skin and difficulty concentrating.

Inflammatory conditions

Rheumatoid arthritis and other inflammatory conditions can cause swelling around joints and tendons, narrowing the space available for nerves. Pain, prolonged morning stiffness and swollen hand joints may provide additional clues.

Medication, alcohol and other causes

Peripheral nerve damage may also be associated with:

excessive alcohol consumption;
certain chemotherapy medicines;
some antibiotics and other prescribed medicines;
kidney or liver disease;
autoimmune conditions;
infections;
inherited neurological disorders.

Do not stop prescribed medication without speaking to the clinician responsible for it.

The NHS guide to peripheral neuropathy explains its symptoms, causes and assessment.

Could poor circulation or Raynaud’s cause it?

People often describe any tingling as “poor circulation”, but recurrent finger numbness is frequently caused by nerve compression rather than blocked blood vessels.

Raynaud’s phenomenon temporarily reduces blood flow to the fingers, usually in response to cold or emotional stress. During an episode, the fingers may:

turn white, blue and then red;
feel cold or numb;
tingle or throb as blood flow returns;
become painful.

Night-time Raynaud’s symptoms may be triggered by a cold bedroom, but the colour change and temperature sensitivity usually distinguish it from carpal tunnel syndrome.

Arrange a medical review if Raynaud’s begins for the first time after age 30, affects only one side, is becoming worse or is associated with joint pain, skin changes, ulcers or muscle weakness.

Sudden severe pain, marked paleness or blueness that does not improve with gentle warming requires urgent assessment. Read more in the NHS guide to Raynaud’s.

When should pins and needles be treated as urgent?

Most night-time hand tingling is not an emergency. The manner in which it begins and the other symptoms occurring with it are more important than the tingling alone.

Call 999 immediately if sudden numbness or weakness is accompanied by:

one side of the face drooping;
inability to raise or keep up one arm;
slurred, confused or absent speech;
numbness or weakness down one side of the body;
sudden loss or blurring of vision;
severe dizziness or loss of balance;
a sudden, exceptionally severe headache.

These can be signs of a stroke or transient ischaemic attack. Call even if the symptoms disappear, as it is not possible to distinguish a TIA from a stroke safely at home. Follow the NHS FAST guidance for stroke symptoms and see our guide to stroke and TIA warning signs.

Seek urgent medical help through NHS 111, an urgent treatment centre or A&E, depending on severity, if:

tingling follows a serious neck, arm or wrist injury;
the hand becomes cold, blue, very pale or severely painful;
you suddenly cannot move the hand or fingers normally;
numbness rapidly spreads or worsens;
there is a deep cut with loss of feeling or movement;
weakness occurs with difficulty walking or bladder or bowel changes;
you have severe swelling, redness or fever.

When should you make a routine GP appointment?

Arrange an appointment if pins and needles:

keep returning or wake you regularly;
last after you change position;
are present during the day as well as at night;
consistently affect the same fingers;
are occurring in both hands or the feet;
are accompanied by pain in the neck, shoulder, elbow or wrist;
are associated with reduced grip or hand clumsiness;
make you drop objects;
are gradually becoming more frequent;
started after beginning a medicine;
occur alongside possible diabetes, thyroid or vitamin-deficiency symptoms.

Persistent numbness is particularly important. Pain may come and go, but reduced feeling can increase the risk of burns and injuries because the hand no longer detects heat or damage normally.

Contact a clinician promptly if you notice visible wasting at the base of the thumb or between the hand bones. This may indicate more advanced nerve compression.

What can you try at home?

If symptoms are mild, short-lived and clearly related to sleep position, changing how you sleep may help.

Keep the wrists neutral

Avoid curling the hands underneath your chin, body or pillow. Try to keep each wrist in a straight, relaxed position rather than bent forwards or backwards.

A neutral-position wrist splint worn at night can help suspected carpal tunnel syndrome. It should support the wrist without being painfully tight. Remove it and seek advice if it makes tingling, swelling, pain or colour changes worse.

Avoid prolonged elbow bending

If the little and ring fingers are affected, avoid sleeping with the elbow tightly flexed or resting against a hard bed frame. A loose towel around the elbow may help remind you not to bend it fully.

Review daytime activities

Symptoms may be aggravated by prolonged gripping, vibrating tools, repeated wrist movements or leaning on the elbows. Take regular breaks and vary tasks where possible.

Computer use does not automatically cause carpal tunnel syndrome, but an uncomfortable position can aggravate existing symptoms. Keep the keyboard and mouse close enough that your wrists and elbows remain relaxed.

Keep a symptom record

For one or two weeks, note:

which hand is affected;
which fingers tingle;
how long symptoms last;
whether shaking the hand helps;
whether the neck, elbow or wrist hurts;
which sleeping and daytime positions trigger symptoms;
whether grip strength has changed.

This can help a clinician distinguish positional pressure from a more persistent nerve problem.

Avoid aggressively shaking, stretching or massaging a hand that is severely painful, injured, weak or persistently numb.

Do hand exercises help?

Gentle movement may reduce stiffness and help some people with mild nerve-compression symptoms, but exercises cannot correct every cause. Stop if they increase pain, numbness or tingling.

Gentle wrist movement

Rest the forearm on a table with the hand free.
Slowly move the wrist forwards and backwards through a comfortable range.
Repeat five to ten times without forcing the movement.

Finger opening and closing

Begin with the fingers comfortably straight.
Make a loose fist without squeezing hard.
Open and gently spread the fingers.
Repeat five to ten times.

Posture breaks

If symptoms occur with desk work, relax the shoulders, bring the chin gently backwards and allow the elbows to rest near the sides. Regular changes of position are usually more useful than trying to maintain one supposedly perfect posture.

Nerve-gliding exercises are sometimes recommended for carpal or cubital tunnel syndrome, but technique matters. A physiotherapist, occupational therapist or hand specialist can show an appropriate exercise and determine whether it suits your condition.

Do not perform forceful neck stretches if tingling travels from the neck down the arm, particularly when weakness or severe pain is present.

How will a clinician investigate night-time tingling?

A GP or other clinician will ask when the symptoms began, which fingers are involved and whether there is pain, weakness or loss of coordination.

The examination may include:

checking sensation in different fingers;
testing grip and individual hand muscles;
examining the wrist and elbow;
checking reflexes;
assessing neck movement;
looking for joint swelling or muscle wasting;
checking pulses, temperature and skin colour.

Blood tests may be appropriate when symptoms suggest diabetes, vitamin B12 deficiency, thyroid disease, inflammation, kidney disease or another systemic cause.

Nerve-conduction studies can measure how quickly electrical signals travel through the nerves. They may help confirm carpal tunnel syndrome, ulnar neuropathy or more widespread nerve damage.

Ultrasound may show swelling or compression of a nerve. An MRI scan is not routinely necessary for straightforward positional tingling or typical mild carpal tunnel symptoms, but it may be considered if a neck, spinal cord or structural problem is suspected.

How are persistent symptoms treated?

Treatment depends on the underlying cause rather than the sensation itself.

Cause	Possible treatment
Positional nerve pressure	Changing sleep position and avoiding prolonged compression
Carpal tunnel syndrome	Night splint, steroid injection or surgery when appropriate
Ulnar nerve compression	Avoiding elbow pressure, night positioning, therapy or surgery in severe cases
Nerve irritation in the neck	Activity advice, pain relief, physiotherapy and occasionally specialist treatment
Diabetes	Blood-glucose management, foot and hand protection, and treatment of nerve pain
Vitamin B12 deficiency	Replacement tablets or injections and treatment of the cause
Underactive thyroid	Thyroid-hormone replacement when confirmed
Raynaud’s	Keeping warm, avoiding triggers and sometimes medication

Long-standing compression can cause permanent loss of sensation or muscle strength. Early assessment becomes more important when weakness, continuous numbness or muscle wasting develops.

Frequently asked questions

Why do I wake with both hands numb?

Both wrists may be bent or compressed during sleep, particularly if you tuck your hands under a pillow. Bilateral carpal tunnel syndrome is also common. Tingling in both hands and feet may point towards a more general nerve or medical condition.

Which fingers are affected by carpal tunnel syndrome?

It typically affects the thumb, index finger, middle finger and thumb-side of the ring finger. The little finger is usually spared because it is supplied by the ulnar nerve.

Why do my little and ring fingers go numb at night?

This pattern commonly suggests pressure on the ulnar nerve, particularly when you sleep with the elbow tightly bent. Persistent symptoms or hand weakness need assessment.

Can sleeping on your arm cause pins and needles?

Yes. Pressure on a nerve or its blood supply can cause temporary tingling. It should usually improve within a few minutes after changing position.

Can anxiety cause tingling hands?

Anxiety and rapid breathing can cause tingling, often around both hands and the mouth. However, anxiety should not be assumed to explain repeated symptoms that follow a particular nerve pattern, cause weakness or occur independently of anxious episodes.

Can dehydration cause tingling?

Ordinary mild dehydration is not a common explanation for repeated finger numbness at night. Severe fluid or electrolyte disturbances can affect nerves and muscles but usually cause other symptoms as well.

Does menopause cause pins and needles?

Some people report altered skin sensations around perimenopause or menopause, and hormonal changes may contribute indirectly to carpal tunnel syndrome. Persistent tingling still deserves assessment rather than being attributed automatically to menopause.

Can pregnancy cause numb hands at night?

Yes. Fluid retention during pregnancy can increase pressure in the carpal tunnel. Night splints may help, and symptoms often improve after birth. Speak to your midwife or GP if symptoms are persistent, painful or associated with weakness.

Should I wear a wrist splint to bed?

A neutral-position night splint can help mild carpal tunnel symptoms. It should not be excessively tight, and it is less likely to help if the tingling comes from the elbow, neck or a generalised neuropathy.

When should I worry about numbness in one hand?

Seek emergency help if it starts suddenly with arm weakness, facial drooping, speech problems or other stroke symptoms. Arrange a routine assessment when it persists, repeatedly wakes you or affects grip and coordination.

Can low vitamin B12 cause tingling?

Yes. Vitamin B12 deficiency can damage nerves and cause tingling, numbness, balance problems and weakness. A blood test and clinical assessment can help establish whether it is responsible.

Will night-time pins and needles go away?

Positional tingling usually resolves after the pressure is removed. Carpal tunnel syndrome and other nerve conditions may fluctuate but can worsen without appropriate changes or treatment, especially once continuous numbness or weakness develops.
