What causes pins and needles?

Pins and needles happen when pressure on a nerve temporarily interrupts its signals — this is why your foot "falls asleep". Moving relieves the pressure and sensation returns, sometimes with tingling.

When is numbness a sign of diabetes?

Long-term high blood sugar can damage peripheral nerves, often causing numbness or burning in the feet. Regular foot checks are important if you have diabetes.

Can a trapped nerve cause tingling?

Yes — conditions such as carpal tunnel syndrome or sciatica compress nerves and cause tingling, pain or weakness along the nerve path. A GP or physiotherapist can assess this.

Should I worry about numbness in both hands at night?

Night-time hand tingling is common with carpal tunnel syndrome. If it is frequent or you drop objects, see a GP — treatment ranges from splints to surgery in severe cases.

Numbness and tingling: When to See a GP

Quick answer

What could numbness and tingling mean?

Numbness and tingling are altered sensations that happen when a nerve is compressed, irritated or damaged — often simply from sitting or sleeping awkwardly. The feeling usually passes once you move and the pressure eases. Persistent, one-sided or spreading numbness, especially with weakness, needs a GP assessment to rule out nerve compression, diabetes or stroke.

Understanding numbness and tingling

Numbness and tingling happen when nerves are compressed, irritated or damaged. Temporary tingling after sitting or lying in an awkward position is common and harmless. When symptoms persist, affect one side of the body or come with weakness, a medical assessment helps identify treatable causes.

Common causes of numbness and tingling

Trapped nerves are a frequent cause — carpal tunnel syndrome, pressure on the ulnar nerve at the elbow and sciatica all produce tingling in predictable areas. Diabetes can lead to peripheral neuropathy, a form of nerve damage that often starts in the feet.

Vitamin B12 deficiency, drinking too much alcohol and some infections can also affect the nerves. Multiple sclerosis causes a range of neurological symptoms, including numbness.

Self-care and prevention of numbness and tingling

Avoid prolonged pressure on your nerves by changing position regularly, using an ergonomic set-up at work and taking breaks from repetitive tasks. If you have diabetes, keep your blood sugar well controlled and inspect your feet daily for injuries you may not be able to feel.

When to seek urgent help for numbness and tingling

Sudden numbness or weakness on one side of the body, facial droop, speech problems or confusion are symptoms of a stroke and should be treated as an emergency. Progressive weakness, numbness affecting both sides of the body, or loss of bladder or bowel control with back pain all need urgent assessment.
