When numbness and tingling in hands or feet needs a doctor — soon
·Sudden one-sided numbness with weakness or speech change (call ambulance)
·Loss of bladder or bowel control
·Numbness spreading rapidly over hours/days
·Numbness with severe back pain
·Numbness in both feet with diabetes
This is general guidance, not a diagnosis. If you have any of the above, book a same-day consult or seek urgent care.
Common causes a physician will look for
·Vitamin B12 deficiency (very common in Indian vegetarians)
·Diabetic peripheral neuropathy
·Carpal tunnel syndrome (typical 'morning tingling' in the hand)
·Cervical or lumbar spine nerve compression
·Hypothyroidism, alcohol-related, or medication side effect
What to expect at the consult
Examination of sensation, reflexes, and strength; HbA1c, B12, Vitamin D, TSH; and a referral for nerve conduction or imaging only if indicated. Most causes are reversible if caught early.
Frequently asked
Could tingling be from low B12?
Yes — especially in vegetarians. A single B12 test and a course of replacement frequently solves the problem completely.
