Pain in the joints is a sign of Decompression Sickness Type 1.

• A. Type 2
• B. Type 1
• C. Inner Ear
• D. Cardiopulmonary

Answer: (B)

Joint pain is a hallmark feature of Decompression Sickness Type 1. This milder form mainly affects the musculoskeletal system and skin, with nitrogen bubbles forming in tissues around joints and causing the deep, aching “bends” you feel in the shoulders, elbows, hips, or knees. It may also come with skin itching or mottling, but there aren’t dominant brain, spinal, or lung symptoms. Type 2, by contrast, involves the nervous system and/or cardiopulmonary system, producing signs like dizziness or confusion, chest pain or breathing trouble, and sometimes inner‑ear problems. So when the presenting sign is joint pain, Type 1 is the best fit.
