Which symptom is NOT associated with type I DCS?

• A. Joint pain
• B. Severe itching
• C. Fatigue
• D. Skin rash

Answer: (B)

Type I decompression sickness (DCS), often referred to as "the bends," primarily affects the joints and muscles, leading to symptoms such as joint pain and sometimes fatigue. A skin rash can also be observed due to the release of nitrogen bubbles into the bloodstream during ascent after a dive.

Severe itching, however, is not a typical symptom associated with type I DCS. While other symptoms may arise from various conditions, itching itself is more commonly related to type II DCS or other diving-related issues. Therefore, recognizing the hallmark symptoms of type I DCS helps in identifying its presence and differentiating it from other related conditions. Understanding these symptoms is crucial for divers to seek appropriate medical attention promptly.
