This condition occurs when nitrogen bubbles form in the bloodstream or tissues as a diver ascends too quickly after spending time at depths under pressure. The formation of these bubbles can lead to various physiological problems, and one of the most common manifestations is pain in the joints, similar to the pain experienced in other conditions like arthritis.

In addition to joint pain, fatigue can occur as the body responds to the presence of these bubbles and attempts to repair any damage caused by the rapid ascent. The discomfort and systemic effects of decompression sickness can lead to a general sense of fatigue or malaise, as the body struggles to manage the outcoming nitrogen and its effects on the circulatory and nervous systems.

The other choices do not align with the typical presentation of decompression sickness. While an increased heart rate can occur as part of the body’s stress response, it is not a definitive sign of decompression sickness on its own. Improved vision is generally not associated with this condition; in fact, visual disturbances may occur due to various factors, but they are not characteristic of decompression sickness.
