What is a common sign of DCS that divers should be aware of?

Joint pain, commonly referred to as "the bends," is a classic sign of decompression sickness (DCS), which occurs when nitrogen bubbles form in the body due to rapid ascent after diving. As divers breathe compressed air or nitrox, the nitrogen is absorbed into the body tissues. If a diver ascends too quickly, the dissolved nitrogen comes out of solution and forms bubbles, leading to various symptoms.

Joint pain is particularly notable because it often manifests as a deep, aching sensation in the joints, which can be exacerbated with movement. Other symptoms of DCS may vary but often include fatigue, dizziness, and difficulty breathing, yet joint pain remains one of the most distinctive and recognizable indicators. It is vital for divers to recognize this symptom early and seek immediate medical attention to prevent further complications associated with DCS.
