Correct answer: B — Carpal tunnel syndrome associated with vibrating tool use

Median nerve symptoms affecting the thumb, index and middle fingers with nerve-conduction confirmation indicate carpal tunnel syndrome. Vibrating hand tools are a recognised occupational risk and may make the condition reportable where criteria are met. HAVS would include vascular blanching or diffuse sensory symptoms linked to vibration. Ulnar neuropathy would involve the little finger and ulnar border of the hand.
