What is the most common symptom associated with DCI?

Decompression Illness (DCI), often manifested as Decompression Sickness (DCS), primarily presents with joint and muscle pain, often described as deep, aching discomfort. This pain is typically localized and is commonly referred to as "the bends." The symptom arises due to the formation of nitrogen bubbles in the tissues and bloodstream following a rapid ascent after deep dives.

Pain in DCI is often severe and can significantly hinder movement, thereby alerting divers to potential serious issues requiring immediate attention. Unlike other symptoms, such as numbness or constitutional symptoms like fatigue and nausea, pain is a hallmark indicator that divers should recognize as an urgent sign of possible DCI. Understanding this symptom is crucial because timely recognition and treatment can prevent further complications associated with the condition.

While other symptoms can also accompany DCI, the predominance of pain makes it a central focus of initial assessment for anyone suspected of experiencing decompression sickness.
