Tingling in your hands and feet, that “pins and needles” feeling, happens when nerves are pressed, irritated or damaged, or when blood flow to them drops. Brief tingling after sitting, crossing your legs or sleeping on your arm is normal, harmless and fades within minutes.
Tingling that lasts, keeps coming back or spreads is often a sign of peripheral neuropathy, diabetes, vitamin B12 deficiency or nerve compression, and should be checked by a doctor. Finding the cause early helps you protect nerve function and stop the damage from getting worse.
If tingling starts suddenly on one side of your body, or comes with face drooping, weakness, trouble speaking or vision loss, call 911. These can be signs of a stroke.
Tingling, which doctors call paresthesia, means the signals between your nerves and your brain are being disrupted. Nerves carry messages between your brain, spine and body. When those signals are blocked or irritated, you feel tingling, numbness, burning or a “buzzing” sensation.
It usually shows up in the hands and feet first because those nerves are the longest in the body and the farthest from the spine.
Short-lived pins and needles in your hands and feet comes from pressure on a nerve or a brief drop in circulation. Tingling that lasts for days, keeps returning, or comes with numbness, burning or weakness usually points to an underlying condition affecting the nerves themselves.
Most ongoing tingling and numbness in the hands and feet comes from one of the causes below. Many people have more than one at the same time, such as diabetes and low B12.
Peripheral neuropathy, or damage to the nerves outside the brain and spinal cord, is the most common reason for ongoing tingling in both hands and feet. The typical pattern starts in the toes, affects both sides evenly and slowly spreads upward, later reaching the fingers in a “stocking-glove” pattern.
Diabetes is the leading cause, responsible for more than half of cases in the U.S. and other Western countries. Over time, high blood sugar damages the small nerves in the feet and hands.
Vitamin B12 deficiency is one of the most common deficiencies behind tingling in hands and feet, and one of the most treatable. B12 helps protect the coating around your nerves. People who take metformin, use acid-reducing medicines (proton pump inhibitors) long term, follow a vegan diet or have trouble absorbing nutrients are at higher risk.
Low levels of vitamin B1 (thiamine), folate or copper can cause similar symptoms. Low copper is often caused by taking in too much zinc, for example from some denture creams.
Vitamin B6 works both ways. Too little B6 can cause tingling, but too much B6 (pyridoxine) is a well-known cause of neuropathy. Many over-the-counter “nerve support” products contain high doses of B6.
Carpal tunnel syndrome presses on the median nerve in the wrist and causes tingling in the thumb, index and middle fingers, often worse at night. A pinched nerve in the neck, or sciatica in the lower back, can send tingling down an arm or leg.
An underactive thyroid (hypothyroidism) can cause neuropathy and also raises the risk of carpal tunnel syndrome. Chronic kidney disease and liver disease let toxins build up in the blood, which can damage nerves over time.
Some chemotherapy drugs, HIV medicines, the heart rhythm drug amiodarone, certain antibiotics and some anti-seizure drugs can cause neuropathy. Long-term heavy alcohol use damages nerves directly and lowers B vitamin levels.
Multiple sclerosis, lupus, rheumatoid arthritis, Sjögren’s syndrome and Guillain-Barré syndrome can all cause tingling. Tingling that rises quickly from the feet upward with leg weakness needs emergency care, as it can be a sign of Guillain-Barré syndrome. If it comes with trouble breathing or swallowing, call 911.
Peripheral artery disease and Raynaud’s phenomenon reduce blood flow to the fingers and toes. This can cause tingling, coldness or color changes, often triggered by cold or stress.
Yes, anxiety and stress can cause tingling in the hands and feet. During a panic attack or fast breathing (hyperventilation), carbon dioxide levels drop and nerves become more excitable, which can cause tingling in the hands, feet or face.
This tingling usually eases as you calm down. If it happens without anxiety, or doesn’t go away, other causes should be ruled out.
Nighttime tingling is common with carpal tunnel syndrome, because the wrists stay bent during sleep, and with diabetic neuropathy, which often feels worse when you are resting. Sleeping on an arm can also cause short-lived tingling.
Random tingling that comes and goes is often linked to posture, repetitive movements, anxiety or changes in circulation. In early neuropathy, symptoms may also come and go before they become constant. Keeping a simple log of when it happens helps your doctor find the cause faster.
Tingling in both hands and feet that started in the toes usually points to a body-wide cause, such as diabetes, B12 deficiency, alcohol, kidney or thyroid disease, or medication side effects, rather than one pinched nerve.
Tingling in the hand and foot on the same side of the body is not typical of neuropathy. If it starts suddenly, treat it as a possible stroke and call 911. If it has built up over time, it still needs a prompt medical exam to check the brain and spinal cord.
Call 911 or go to the ER if tingling:
See your primary care doctor if tingling:
For most people, the first step is your primary care doctor. They will ask about your symptoms, medications, alcohol use and health history, do a physical exam and order basic blood tests:
If these results don’t explain your symptoms, your doctor will refer you to a neurologist, the specialist who diagnoses and treats nerve problems.
Most typical cases don’t need nerve tests or scans. A neurologist may recommend nerve conduction studies and EMG, or an MRI of the brain or spine, when the pattern is unusual, for example:
Treatment aims to fix or control the cause and stop nerve damage from getting worse. Nerve damage that is already present rarely reverses completely, so how much you recover depends on the cause and how early it is treated. Early treatment helps most with B12 deficiency.
In about a quarter of people, no cause is found even after a full workup. Symptoms can still be managed, and your doctor will keep monitoring for changes.
Don’t take high-dose B6 or “nerve support” supplements unless your doctor recommends them.
If tingling is painful or burning, prescription treatments can help. These include gabapentin, pregabalin and duloxetine, as well as lidocaine or capsaicin creams and patches. Opioids are not recommended for nerve pain.

Numbness means you may not feel a cut, blister or burn, and neuropathy raises your risk of falling. This matters most if you have diabetes.
Tingling in your hands and feet is easy to ignore until it affects your sleep, balance or grip. Finding and treating the cause is the best way to stop nerve damage from getting worse.

Vitamin B12 deficiency is the most common one. Low B1 (thiamine), folate, copper or B6 can also cause tingling. Too much B6 from supplements can cause tingling too, so get a blood test before taking any vitamins for nerve symptoms.
Tingling in both hands and feet is rarely a stroke. Stroke-related tingling usually starts suddenly on one side of the body, often with face drooping, arm weakness, trouble speaking or vision loss. If you notice those signs, call 911 right away.
Not always. Short-term tingling often comes from reduced blood flow or pressure on a nerve, such as when you sit in one position too long. Persistent or spreading tingling, however, usually indicates nerve irritation or injury and should be checked by a doctor.
Tingling from posture or brief nerve pressure fades quickly. Tingling from diabetes, vitamin deficiency or other conditions usually needs treatment of the cause. Treatment can stop it from getting worse, but existing nerve damage may not fully heal, so earlier is better.
Yes. Low calcium or magnesium can cause tingling, often around the mouth and in the fingers, along with muscle cramps. Dehydration alone doesn’t usually cause tingling. Electrolyte problems show up on routine blood tests and are usually easy to correct.
