What is the most common symptom of Decompression Sickness (DCS)?

Joint pain is recognized as the most common symptom of Decompression Sickness (DCS), often referred to as "the bends." This condition occurs when a diver ascends too quickly, causing nitrogen that was absorbed at higher pressures to come out of solution in the body, forming bubbles. These bubbles can cause a range of symptoms, but joint pain, especially in the elbows, shoulders, and knees, frequently presents as one of the earliest and most noticeable indicators of DCS.

The pain is usually characterized as a deep, aching sensation and can vary in intensity. It is important for divers and medical professionals to recognize this symptom promptly, as timely treatment is essential to prevent further complications from the condition. While the other symptoms listed, such as marbling, paresthesia, and weakness, can occur with DCS, the predominance of joint pain makes it a critical symptom to be aware of in the assessment and management of the condition.
