Most pins and needles is harmless. If you have been sitting on a leg or sleeping on an arm, the prickling usually fades within minutes. Both the NHS and the HSE describe this as the everyday cause. Pressure cuts the blood supply to a nerve, and the feeling stops once the pressure is off.
Tingling that keeps coming back, lasts a long time or never fully goes is different. That is worth a GP appointment, because the common longer-term causes are often findable and treatable. They include a squeezed nerve at the wrist, nerve damage from diabetes, low B12 or alcohol, and the physical side of anxiety. A small number of causes are emergencies, so those come first.
Call 112 or 999 in Ireland, 999 in the UK, or 911 in the US if you have:
The last three can mean the nerves at the bottom of the spine are being compressed. That needs hospital treatment as soon as possible. Do not drive yourself. Ask someone to drive you, or call an ambulance.
Get an urgent GP appointment (out-of-hours GP if needed, or NHS 111 in the UK) if tingling in your feet and hands is followed by muscle weakness. This can be Guillain-Barré syndrome, which is rare but needs hospital treatment.
See a GP soon if pins and needles is constant or keeps coming back. The same applies to a cut or sore on your foot that is not healing.
Pins and needles is a nerve sending an abnormal signal. Doctors call it paraesthesia. The cause can be a pressed nerve, a damaged nerve, or a problem in the spinal cord or brain. The groups below are not a self-diagnosis checklist. They show what is worth mentioning to a doctor.
The familiar kind lasts a few minutes and stops when the weight comes off. If that is the whole story, nothing further is needed.
This is pressure on the median nerve as it passes through a tunnel in your wrist. It causes tingling, numbness and pain in the hand and fingers. Some people notice a weak thumb or difficulty gripping. Symptoms often start slowly, come and go, and are usually worse at night.
Risk is higher in pregnancy, if you are overweight, or if you often bend your wrist, grip hard or use vibrating tools. Arthritis, diabetes, a past wrist injury and a parent or sibling with it also raise the risk. The NHS notes it sometimes gets better by itself within a few months, particularly in pregnancy.
The NHS lists a trapped nerve in the back or neck as a cause of long-lasting pins and needles. The best-known example is sciatica, felt in the bottom and the back of one leg, often down to the foot. It may be worse when moving, sneezing or coughing. Most sciatica improves within weeks to a few months.
Tingling during anxiety is a real physical symptom. The NHS lists numbness or pins and needles, and tingling in the fingers, among panic attack symptoms. These sit alongside a racing heart, shortness of breath, trembling and a sense of dread. Most panic attacks last 5 to 20 minutes.
The NHS also links breathing too quickly, with trembling hands and pins and needles, to hyperventilation. If this pattern sounds familiar, our guide to the difference between a panic attack and panic disorder explains when it becomes something to treat.
One caution matters here. A history of anxiety does not explain away new one-sided numbness, weakness or any of the warning signs above. Those need checking regardless.
Peripheral neuropathy means damage to the nerves outside the brain and spinal cord. The NHS estimates that almost 1 in 10 people aged 55 or over in the UK are affected. The main symptoms are numbness and tingling in the feet or hands, burning or shooting pain, loss of balance and muscle weakness.
The most common type affects the longest nerves first. So it usually starts in the feet, feels as if it spreads upwards over time, and reaches the hands later.
The causes most worth finding:
In some people no cause is found, which is called idiopathic neuropathy. We go into neuropathy in more depth in numb or burning feet: the causes worth finding. That article includes our own position on vitamin B6. Our B12 article covers who is most at risk of low B12.
Numbness or tingling in different parts of the body is one of the most common symptoms of MS. Others include fatigue, vision problems and feeling off balance. The NHS stresses that these symptoms are common, have many causes, and do not mean you have MS. They are still worth getting checked. Our MS article covers what is known about risk and treatment.
Sudden one-sided numbness or weakness must never wait. A transient ischaemic attack (TIA), or mini-stroke, causes the same symptoms but they pass within minutes or hours. The HSE says a TIA should still be treated as a medical emergency, with specialist review within 24 hours. Our stroke article covers the FAST signs and the risks you can change.
This is compression of the nerves at the bottom of the spine. Its warning signs are the leg, saddle and bladder or bowel symptoms in the box above. Tingling in the feet on its own is not this. Tingling or weakness in both legs together with any of those signs is an emergency.
This rare condition often starts with tingling in the feet and hands, followed by weakness that usually worsens over 2 to 4 weeks. It usually starts within a few weeks of an infection such as flu or a stomach bug.
Expect questions about where the tingling is, when it started, and whether it comes and goes. You may be asked if it affects one side or both, and what changes it. Work, alcohol, diet, other illnesses and family history may come up too. Bring a list of every medicine and supplement you take.
The examination usually tests sensation, strength and reflexes. Carpal tunnel syndrome can often be diagnosed from your symptoms and a check of your hand.
Blood tests are common, especially for diabetes and B12. Our guide to blood tests worth asking about covers preparing and reading results.
Depending on what the GP finds, next steps can include:
In the UK, many areas let you refer yourself to NHS physiotherapy for back and joint problems without seeing a GP first. In Ireland and the US, start with your GP or primary care doctor.
These steps come from NHS and HSE guidance. They do not replace getting checked.
Yes. The NHS lists pins and needles and tingling fingers among panic attack symptoms, and links fast breathing to them. Anxiety should not be assumed, though. Sudden, one-sided or worsening symptoms need checking first.
Sleeping on an arm is a common reason. Carpal tunnel syndrome is another, and its symptoms are usually worse at night. If it keeps happening, or you notice a weak grip, see your GP.
Yes. B12 deficiency can cause pins and needles, numbness, weakness and balance problems. Some damage can become permanent if untreated, so a blood test is worth having rather than guessing.
Seek emergency help for severe or worsening weakness or numbness in both legs. The same applies to numbness around the genitals or bottom, or new bladder or bowel problems. Tingling that slowly creeps up both feet is not an emergency. It does need a GP visit to look for causes such as diabetes.
