Pins and Needles from Vitamin Deficiency

Vitamin B12 supports healthy blood cells and nerve function. When levels are low, tingling or reduced sensation may appear in the hands or feet and may be accompanied by tiredness, a sore tongue, pale skin, memory changes or balance problems. The pattern is not specific to deficiency: Peripheral Neuropathy, Type 2 Diabetes and Hypothyroidism can also affect nerves. Restricted diets, problems absorbing nutrients, stomach or bowel conditions, and some medicines can make deficiency more likely. A symptom alone cannot identify the cause.

Book an appointment if tingling persists, spreads or occurs with weakness, clumsiness or balance changes. Tell the clinician about your diet, digestive symptoms, previous stomach or bowel surgery, medicines and any supplements you take. Blood tests can check Vitamin B12 and related findings while the examination looks at sensation, reflexes and strength. Avoid starting high-dose supplements before advice, because they may alter test results or mask another deficiency. Treatment depends on the cause and may involve dietary changes, tablets or injections.

Call emergency services for sudden tingling or numbness with facial drooping, one-sided weakness, speech difficulty, confusion, severe dizziness or a sudden severe headache. These symptoms may indicate Stroke or Transient Ischaemic Attack. Seek prompt assessment for rapidly worsening balance, inability to walk, new loss of bladder or bowel control, or marked weakness. Do not wait for a vitamin test when neurological symptoms start abruptly.

Ask whether your symptoms fit Vitamin B12 Deficiency or another nerve condition, which tests are appropriate, whether supplements should wait until testing, and how treatment will be monitored. Also ask whether your medicines, diet or digestion could be affecting absorption.
