Sickle Cell Crisis
The hallmark of sickle cell disease is a group of devastating symptoms known collectively as a sickle cell crisis (also sometimes known as a vaso-occlusive crisis). Sickle cell crises are episodes of pain that occur with varying frequency and severity in different patients and are usually followed by periods of remission. Severe sickle cell pain has been described as being equivalent to cancer pain and more severe than postsurgical pain. It most commonly occurs in the lower back, leg, abdomen, and chest, usually in two or more locations. Episodes usually recur in the same areas.
The risk for a sickle cell crisis is increased by any activity that boosts the body's requirement for oxygen, such as illness, physical stress, or being at high altitudes. In more than half the cases, however, the trigger is unknown. Acute chest syndrome is a particularly serious complication of sickle cell crisis. It occurs in the lungs and can be extremely serious and even life threatening.
