Clinical Classification Guidelines
Medical Intelligence & Overview

Key Symptoms: Numbness, tingling, or a burning sensation in the thumb, index, middle, and part of the ring finger Weakness in the muscles of the thenar eminence, leading to difficulty gripping or pinching objects Pain along the median nerve distribution, which may worsen with activity or at night Loss of fine motor skills affecting hand coordination Decreased sensation or abnormal sensations in the affected areas Possible muscle wasting in the thenar muscles if the nerve lesion persists
