What are the types of symptoms associated with Type 1 DCS?

In Type 1 Decompression Sickness (DCS), symptoms primarily manifest as pain and other physical changes in the body resulting from the formation of bubbles in tissues or joints. The symptoms most commonly associated with Type 1 DCS include pain that is often described as deep, aching, or sharp, typically located in the joints or muscles. Swelling and marbling of the skin may also present as signs of this condition.

This choice correctly identifies the hallmark indicators of Type 1 DCS, which are related to the emergence of nitrogen bubbles during rapid decompression after a dive. These bubbles can cause localized pain and may affect the skin's appearance, leading to the marbling effect.

Other options presented do not accurately represent Type 1 DCS. Difficulty breathing pertains more to Type 2 DCS, where there are signs of neurological or pulmonary complications. While nausea and fatigue could occur in various scenarios, they are not specific symptoms of Type 1 DCS. Lastly, tremors and convulsions are associated with more severe types of DCS or other medical emergencies but are not typical symptoms of Type 1 DCS, which focuses more on musculoskeletal pain.
