Which symptom is NOT associated with decompression sickness?

Decompression sickness, often referred to as "the bends," is primarily associated with a range of symptoms that result from the formation of gas bubbles in the bloodstream and tissues due to a rapid decrease in pressure.

Localized joint pain, altered level of consciousness, and skin rashes are all recognized symptoms of decompression sickness. Localized joint pain can occur as nitrogen bubbles accumulate in the joints, leading to discomfort and swelling. An altered level of consciousness might manifest if gas bubbles affect cerebral circulation or function. Skin rashes can occur as a result of the body's response to the presence of gas bubbles.

In contrast, while chest pain can occur in various medical conditions, it is not specifically characterized as a primary symptom of decompression sickness. This symptom more commonly relates to issues like cardiovascular events or respiratory distress, which are not direct manifestations of the bends. Consequently, identifying chest pain as unrelated to decompression sickness aligns with the understanding of the condition's typical symptomatology.
