Numbness / Tingling
Symptoms, Causes & Treatment
Numbness and tingling (paraesthesia) are very common symptoms with many possible causes, from benign nerve compression to serious neurological conditions. Most cases are non-urgent, but some require immediate emergency assessment.
What are Numbness & Tingling?
Paraesthesia — abnormal sensations including numbness, tingling, burning, and pins and needles — results from abnormal nerve signal transmission. It can arise from peripheral nerves (neuropathy), nerve roots (radiculopathy), the spinal cord (myelopathy), or the brain (stroke, MS). The distribution and onset pattern are the most important diagnostic clues.
Symptoms of Numbness & Tingling
The pattern of numbness — where it is, how it started, and what else is present — is the most important diagnostic clue.
Numbness or tingling (paraesthesia) in hands, feet, or face · Pins and needles, burning, or crawling sensations · Symptoms in a glove-and-stocking distribution (peripheral neuropathy) · Unilateral face and limb involvement · Electric-shock sensation on neck flexion (Lhermitte’s sign in MS)
Sudden unilateral numbness or weakness (stroke — FAST — call 999) · Progressive bilateral weakness with ascending numbness (Guillain-Barré syndrome) · Numbness after trauma to neck or spine · Loss of bladder or bowel control with numbness (cauda equina syndrome)
Sudden numbness affecting one side of the body, the face, or both sides simultaneously with weakness or speech difficulty — call 999 immediately.
What Causes Numbness & Tingling?
Numbness and tingling arise from disorders of peripheral nerves, the spinal cord, or the brain. Identifying the pattern and distribution guides investigation.
Peripheral neuropathy causes glove-and-stocking numbness and tingling from damage to peripheral nerves. Common causes include diabetes, alcohol excess, vitamin B12 deficiency, hypothyroidism, chemotherapy, and hereditary neuropathies.
Carpal tunnel syndrome (CTS) causes numbness, tingling, and pain in the thumb, index, and middle fingers from median nerve compression at the wrist. Symptoms are often worse at night. Treated with wrist splints, steroid injection, or surgical decompression.
Multiple sclerosis causes focal demyelinating lesions throughout the CNS. Numbness, tingling, and Lhermitte’s sign (electric shock on neck flexion) are common presenting features. Early diagnosis allows disease-modifying therapy to slow progression.
Cervical or lumbar disc herniation can compress nerve roots, causing dermatomal numbness and tingling. C6 compression causes thumb and index finger symptoms; L4/5 compression causes lateral calf and foot symptoms.
TIA and ischaemic stroke cause sudden unilateral numbness or weakness. Transient numbness that resolves within 24 hours represents a TIA — a medical emergency requiring same-day assessment to prevent stroke.
Vitamin B12, B1 (thiamine), and B6 deficiency cause peripheral neuropathy with numbness and tingling. B12 deficiency also causes subacute combined degeneration of the spinal cord. Deficiencies are easily treated once identified.
Key Risk Factors
Diagnosing Numbness & Tingling
The distribution of numbness (glove-and-stocking, dermatomal, hemibody) and associated features guide which investigations are needed.
Treatment for Numbness & Tingling
Treatment targets the underlying cause. Treating the cause and controlling neuropathic pain are the two main pillars of management.
Supportive Measures
For burning neuropathic pain: topical lidocaine patches, capsaicin cream, and amitriptyline at night all help. For carpal tunnel: night wrist splints. Avoid cold exposure, which worsens neuropathic symptoms. Protect numb feet from injury.
Managing Chronic Neuropathy
Diabetic neuropathy, MS, and hereditary neuropathies require long-term specialist management. Neuropathic pain is treated with gabapentinoids or tricyclics. Regular foot care and review prevents complications of peripheral neuropathy.
When to Seek Help
Sudden unilateral numbness with facial drooping, arm weakness, or speech difficulty — FAST signs of stroke. Call 999 immediately. Every minute matters in stroke treatment.
See a GP if numbness or tingling is persistent, progressive, affecting both feet or hands symmetrically, or accompanied by weakness. Blood tests and neurological assessment can identify treatable causes.
Preventing Numbness & Tingling
Many causes of numbness and tingling are preventable through targeted lifestyle changes and early treatment of underlying conditions.
Optimise blood glucose control in diabetes. HbA1c below 53 mmol/mol (7%) reduces progression of diabetic peripheral neuropathy. Tight control in early neuropathy may partially reverse symptoms.
Measure and maintain vitamin B12 levels. B12 deficiency is common in older adults, vegetarians, and those on metformin or PPIs. Oral or IM B12 supplementation prevents and treats deficiency neuropathy.
Alcohol excess directly damages peripheral nerves. Keep alcohol within recommended limits (14 units/week maximum, with alcohol-free days). In established alcoholic neuropathy, abstinence combined with thiamine supplementation may partially reverse damage.
Take regular breaks from repetitive wrist movements, maintain neutral wrist posture when working at a keyboard, and use ergonomic tools. Wrist splints during repetitive tasks may prevent carpal tunnel syndrome development.
Good foot care prevents complications of peripheral neuropathy. Inspect feet daily for ulcers, calluses, or infection. Wear properly fitted footwear. See a podiatrist regularly. Any foot wound in a neuropathic patient requires urgent review.
Stop smoking to reduce risk of cerebrovascular disease causing sudden neurological symptoms including numbness and weakness. Smoking is the leading modifiable risk factor for TIA and stroke.
Getting Treatment
A GP can arrange blood tests to identify treatable causes, examine for peripheral neuropathy, and refer for nerve conduction studies or neurology assessment. Online consultation is a good first step for non-emergency symptoms.

Numbness & Tingling — Frequently Asked Questions
Common causes include diabetes (the most common cause), vitamin B12 deficiency, carpal tunnel syndrome, cervical disc disease, alcohol excess, and multiple sclerosis. Transient numbness in one hand that spreads rapidly may indicate a TIA and requires same-day emergency assessment.
Seek emergency care (call 999 or go to A&E) if numbness comes on suddenly, affects one side of the body, and is accompanied by weakness, speech difficulty, facial drooping, or vision change. These are stroke warning signs requiring immediate treatment.
Diabetic peripheral neuropathy typically causes numbness, tingling, and burning pain in a glove-and-stocking distribution, starting in the feet. Tight blood glucose control (HbA1c below 53 mmol/mol) is the most important treatment. Neuropathic pain is treated with pregabalin, amitriptyline, or duloxetine.
Carpal tunnel syndrome causes numbness, tingling, and pain in the thumb, index, and middle fingers, classically worse at night or after prolonged wrist use. Night wrist splints often provide significant relief. Steroid injection and surgical decompression are effective for persistent cases.
Yes. MS commonly presents with numbness, tingling, or Lhermitte’s sign (electric shock sensation on bending the neck). These symptoms result from demyelinating plaques in sensory pathways. MRI brain confirms the diagnosis, and disease-modifying therapies slow progression.
B12 deficiency causes peripheral neuropathy and, in severe cases, subacute combined degeneration of the spinal cord. Symptoms include numbness in the hands and feet, poor balance, and cognitive decline. Treatment with IM B12 injections reverses early neurological changes.
Nerve conduction studies (NCS) are the gold standard for diagnosing peripheral neuropathy and carpal tunnel syndrome. They measure conduction velocity and amplitude in motor and sensory nerves. They are painless, performed in a neurology or neurophysiology department.
A GP can arrange blood tests to identify common causes, examine for signs of peripheral neuropathy, and refer for nerve conduction studies or neurology assessment. An online GP consultation is a good first step for non-emergency numbness and tingling.
