In an extremely rare medical case, a scuba diver who descended deep into an underwater cave developed a deadly blood syndrome in which fluid leaked out of his blood vessels.
The syndrome was a strange complication of decompression sickness, or "the bends," in which air bubbles form in the blood as people go from high pressure at depth to low pressure at the surface. The condition usually causes joint pain, dizziness and extreme fatigue. It can be fatal, but most people respond to treatment, which usually involves being placed in a hyperbaric chamber under high pressure and oxygen flow.
