Correct answer: A — Stop injection immediately and withdraw slightly

Sharp radiating pain = possible intraneural injection. ESRA/AAGBI: immediate cessation. Continuing risks fascicular damage and permanent neuropathy. High injection pressures (>15 psi) also indicate intraneural placement. Withdraw slightly, reposition, cautiously re-attempt.
