Numbness and Tingling in Adults

Common Causes

• Carpal tunnel syndrome — Repetitive hand movements at work might compress the median nerve in the wrist, leading to numbness in fingers.
• Diabetes — High blood sugar over time could damage nerves in the feet and hands, a common peripheral neuropathy.
• Herniated disk — A bulging disk in the spine may pinch nerves, causing tingling down arms or legs.
• Vitamin B12 deficiency — Poor diet or absorption problems might lower B12 levels, affecting nerve health.
• Alcohol use — Heavy drinking over time could harm nerves, leading to ongoing numbness.
