Which symptom indicates the need for immediate medical attention in DCS?

Bilateral pain and neurological signs indicate a more severe manifestation of decompression sickness (DCS) that requires immediate medical attention. DCS occurs when nitrogen bubbles form in the body due to rapid changes in pressure, commonly experienced during diving. While joint pain or mild itching may be signs of DCS, they usually reflect less severe forms or mild symptoms that might not require urgent intervention.

In contrast, bilateral pain typically refers to pain affecting both sides of the body, and neurological signs can include symptoms such as confusion, weakness, or changes in sensation. These symptoms suggest a more serious condition known as Type II DCS, which can affect the central nervous system and lead to potentially debilitating or life-threatening consequences if not treated promptly.

Immediate medical treatment is crucial in such cases to prevent further complications, including paralysis or lasting neurological damage. Therefore, recognizing bilateral pain combined with neurological signs as an emergency is essential for the safety of a diver experiencing DCS.
