Correct answer: AGive high-concentration oxygen and obtain urgent diving-medicine advice

The best answer is “Give high-concentration oxygen and obtain urgent diving-medicine advice”. Neurological, musculoskeletal and respiratory symptoms after ascent indicate decompression illness. Give the highest feasible oxygen concentration, support ABCs, keep the patient appropriately positioned and hydrated, and contact a diving-medicine or hyperbaric service urgently for recompression planning. Further diving and reduced ambient pressure during high-altitude transfer can worsen bubble expansion; analgesia alone does not treat the underlying process.
