What should a diver do if they experience symptoms of decompression sickness?

Experiencing symptoms of decompression sickness (DCS) is a serious condition that requires prompt attention. The correct action is to immediately seek medical assistance. Decompression sickness occurs when nitrogen bubbles form in the body due to rapid ascents or missed decompression stops, causing various symptoms that can range from joint pain to severe neurological issues.

Immediate evaluation by medical professionals is essential because DCS can lead to significant complications if not treated appropriately. Treatment often involves hyperbaric oxygen therapy, which is the effective way to eliminate the nitrogen bubbles and provide necessary oxygen to the body tissues affected by DCS.

Continuing to dive or monitoring symptoms isn't advisable; doing so can exacerbate the condition and increase the risk of severe health consequences. Ascending slowly is important during a dive to prevent DCS, but if symptoms already appear, this action alone is inadequate without medical intervention. Taking pain medication might alleviate some discomfort but does not address the underlying issue, which requires professional treatment.
