Which symptom might accompany decompression sickness?

Decompression sickness, often referred to as "the bends," can present a variety of symptoms due to the formation of nitrogen bubbles in the bloodstream or tissues after a diver ascends too quickly. The correct answer highlights itchy skin, which may occur as a result of changes in blood flow and nerve irritation associated with decompression sickness. This symptom is often linked to the release of histamine when nitrogen bubbles interact with the body’s tissues, leading to localized or systemic itching.

In addition, individuals experiencing decompression sickness may have a range of other symptoms such as pain in the joints or muscles, fatigue, and neurological disturbances. However, itchy skin specifically has a notable connection to the symptomatology of decompression sickness and can indicate the presence of bubbles affecting the skin and surrounding tissues. Recognizing this symptom is important for divers, as it can be an early warning signal of a more serious condition and should prompt consultation with a medical professional.
