Which of the following describes common symptoms of decompression sickness?

• A. Joint or muscle pain, dizziness, numbness or tingling, confusion or weakness; rash may occur
• B. Shortness of breath only
• C. Severe chest pain only
• D. High fever only

Answer: (A)

Decompression sickness occurs when dissolved inert gas forms bubbles in tissues and blood as a diver ascends too quickly, triggering symptoms across multiple body systems. The most typical description includes joint or muscle pain, dizziness, numbness or tingling, and confusion or weakness, with a skin rash possible. This broad, multi-system presentation reflects how bubbles can affect joints, nerves, the brain, and the skin. Other options describe symptoms that tend to point to single-organ problems (shortness of breath alone, chest pain alone) or infection (fever), which don’t capture the common, multi-system pattern seen with DCS. Recognizing the combination of musculoskeletal, neurological, and possible cutaneous signs is key for timely treatment.
