Symptoms

The less severe type of DCS is called DCS I. It primarily results in inflammation of muscles, joints, and tendons, resulting in pain and swelling. This is commonly referred to as the bends. Although pain may occur anywhere in the body, it is most common in or near an arm or leg joint. The pain may become more severe over time. Itching, skin mottling, weakness, and fatigue also occur.
  • Stomach pain
  • Back pain
  • Headache
  • Dizziness
  • Confusion
  • Vision problems
  • Vertigo
  • Chest pain and severe coughing
  • Shock
If an individual dives occupationally and has regular exposure to increased pressure, a mild, chronic case of the bends may occur without detection. Over time, this can result in deterioration of affected joints and bones.
