When experiencing DCS, which symptom is commonly associated with the bends?

When experiencing Decompression Sickness (DCS), joint pain is commonly associated with the bends, which is a colloquial term for a type of DCS that affects the joints and muscles. This condition arises when nitrogen bubbles form in the bloodstream and tissues as a result of rapid decompression, typically after a dive or sudden ascent. The release of nitrogen can cause pain in the joints, which has earned the term "the bends" due to the position individuals may take to alleviate the pain, often bending over.

Other symptoms of DCS can indeed include nausea, chest tightness, and dizziness, but joint pain is particularly characteristic of the bends and is one of the most readily recognized symptoms associated with this condition. Understanding this link can help pilots and aircrew recognize the signs of DCS and respond appropriately to prevent further complications.
