Which DCS type is associated with a mottled reddish or purplish rash on the skin?

• A. The Bends
• B. The Chokes
• C. CNS Manifestations
• D. The Creeps

Answer: (D)

Decompression sickness presents with different syndromes depending on where gas bubbles lodge. When bubbles form in the skin’s capillaries, you get the skin-focused manifestation known as the creeps. The hallmark is a mottled reddish or purplish rash on the skin, sometimes accompanied by itching or tingling, due to bubbles causing microcirculatory disturbance and minor bleeding in the skin. This dermatologic sign is distinct from the other DCS types—bends with joint and muscle pain, chokes with chest/pulmonary symptoms, and CNS manifestations with neurological signs—making the mottled skin rash the classic feature of creeps.
