About this symptom
Numbness or pins and needles in the hands and feet may occur with compression of a nerve, nerve-root irritation, peripheral neuropathy, metabolic illness or a central neurological problem. The sensation itself does not establish a diagnosis or indicate a specific treatment.
Clinical features
Which body part is affected matters: individual fingers, one arm, both feet or the sudden loss of sensation on one side point to different possibilities. A clinician asks about duration, posture, pain, weakness and gait changes. Night-time hand numbness can have several causes, including pressure on a nerve.
Important differences and warning signs
Examination assesses sensation, reflexes and muscle strength. Depending on the suspected site and mechanism, selected blood tests, nerve conduction studies, electromyography or imaging may be considered. Not every patient needs all of these investigations.
Assessment and individual care
Management addresses the cause, for example treating nerve compression, correcting an underlying metabolic condition or providing appropriate rehabilitation and symptom relief. Self-prescribed injections for “nerves” are not a substitute for evaluation.

Signs and symptoms
- Pins and needles, burning or reduced feeling in fingers, hands or feet.
- Numbness affecting one limb or a more symmetrical pattern involving both feet.
- Sometimes accompanied by pain, weakness, poor coordination or a changed walking pattern.
Diagnosis and tests
After assessing the location and neurological findings, the clinician may select blood tests, nerve studies or imaging where appropriate.
Care and treatment approaches
Treatment targets the underlying problem. Unnecessary injections or prolonged drug courses without a diagnosis should be avoided.
When to seek urgent care
Sudden numbness of one side of the face or body, especially with weakness, speech or vision changes, requires immediate emergency assessment for stroke. Call 103. Rapidly progressive symmetrical weakness is also urgent.
Frequently asked questions
Why do my hands go numb at night?
Possible reasons include sleeping position and compression of peripheral nerves; the affected fingers and associated symptoms guide assessment.
Does everyone need a spine MRI?
No. The type of investigation depends on the symptom distribution and examination findings.
Is sudden numbness of half the body serious?
Yes. It can indicate stroke, especially with weakness or speech changes. Call emergency services without delay.
