What is a common sign of decompression sickness?

Joint or muscle pain is a common sign of decompression sickness, often referred to as "the bends." This condition occurs when dissolved gases, primarily nitrogen, come out of solution and form bubbles in the body as a diver ascends too quickly. These bubbles can accumulate in tissues and joints, leading to inflammation and pain, typically in the arms and legs. Symptoms may vary from mild to severe and can also include other manifestations like difficulty breathing and neurological issues. Recognizing this pain as a symptom is crucial for immediate treatment and intervention to avoid further complications.

In contrast, increased buoyancy, enhanced vision, and improved balance are not associated with decompression sickness. Buoyancy changes relate to one's position and gear rather than a decompression issue; the eyes' functionality generally remains unaffected, and balance does not improve but may rather be compromised depending on the severity of the symptoms. Understanding the signs and symptoms of decompression sickness, particularly joint or muscle pain, is essential for divers to ensure safety and health during and after dives.
