Understanding the Causes of Finger Numbness

Finger numbness refers to a loss of sensation or feelings in the fingertips. You might touch something extremely cold or hot but feel no response. This condition primarily involves issues with nerves and blood flow in the hands. Sometimes called finger paresthesia, it often results from nerve damage, leading to tingling and numbness. Common causes include alcohol misuse and underlying medical conditions. Diabetes is a significant contributor, as diabetic neuropathy affects nerve health. Other causes include carpal tunnel syndrome, cervical radiculopathy, Raynaud’s disease, strokes, multiple sclerosis, and vascular disorders. Persistent numbness warrants medical attention to prevent complications.
