What is a common sign of decompression sickness?

Pain in the joints is a hallmark symptom of decompression sickness, often referred to as "the bends." This condition occurs when a diver ascends too quickly after spending time at significant depths, causing nitrogen bubbles to form in the body tissues and bloodstream. These bubbles can cause pain, particularly in the joints and muscles, mirroring the sensations of arthritis or intense pain.

While other options might relate to various dive-related health issues, joint pain specifically stands out for its association with decompression sickness. Nausea, dizziness, shortness of breath, and headache can occur for a variety of reasons not limited to decompression sickness and may relate to other diving conditions or general health issues. Thus, recognizing joint pain as a distinct and frequent symptom is crucial for proper identification and response to decompression-related incidents.
