What is the most common skin manifestation of decompression sickness?

The most common skin manifestation of decompression sickness is itching, which is often related to the underlying physiological changes that occur during and after a dive. When divers ascend too quickly, nitrogen that has been dissolved into body tissues during the dive can come out of solution and form bubbles, which can disrupt normal blood flow and cause localized inflammation. This inflammatory response can lead to sensations of itching in the skin.

In the context of diving medicine, the skin manifestations of decompression sickness can vary. Itching can be an early indicator, often accompanied by other symptoms like rash or blisters in more severe cases. However, itching itself is the most frequently reported skin symptom among divers experiencing decompression sickness. Understanding this association helps increase awareness and prompt recognition of symptoms, promoting quicker and more effective intervention.
