Explanation

Sickle cells anemia is an inherited blood disorder that causes chronic anemia, periodic episodes of pain, and other complications. In sickle cell anemia, the red blood cells become rigid and shaped like crescents, or sickles, rather than being flexible and round.

Lack of oxgyen can cause pain and damage in the arms, legs and organs (e.g., spleen, kideney, brain).
