When can tingling in the hands and feet indicate neuropathy?
Brief tingling may resolve after relieving pressure from a position. Persistent or recurrent tingling may relate to neuropathy, nutritional deficiency, medicines or other causes. Sensation alone cannot establish the cause; persistence, weakness or sensory loss needs assessment.

The pattern guides testing
Explain whether symptoms began in feet or hands, whether they are symmetrical, and any burning pain or balance changes. Diabetes, medicines, alcohol and diet are reviewed; glucose, vitamin B12 or nerve tests may be selected when indicated.
Supplements are not always the solution
Avoid guessing with high-dose nerve-vitamin products. Supplementary vitamin B6 can itself cause peripheral neuropathy. Bring product labels because the same ingredient may appear in several supplements.
Protect limbs and seek help
If sensation is reduced, check feet for wounds and avoid direct heat and injurious shoes. A non-healing wound or increasing weakness needs prompt review. Sudden one-sided numbness with speech changes or facial weakness requires emergency help.
