Type II Decompression Sickness (DCS), often referred to as neurological DCS, can manifest through various signs and symptoms that indicate the involvement of the central nervous system. Numbness and tingling are classic symptoms associated with Type II DCS, often resulting from the formation of nitrogen bubbles that can obstruct blood flow to the nervous tissue or irritate the nerve endings.

These sensations typically indicate that neurological elements are affected, which can lead to more severe complications if not addressed promptly. The presence of numbness or tingling in the limbs or other parts of the body represents a disturbance in normal neural function and can serve as a critical warning sign for divers.

In contrast, the other listed options such as fatigue and dizziness, temperature fluctuations, and high blood pressure may be related to various health issues or other types of decompression sickness but are not specific indicators of Type II DCS. Recognizing numbness and tingling as symptomatic of this condition is crucial for early detection and intervention, as it can lead to severe consequences if left untreated during a dive-related incident.
