Sickle Cell Disease (SCD) is a group of inherited red blood cell disorders. In someone who has SCD, the red blood cells become hard and sticky and look like a C-shaped farm tool called a “sickle”.
      The "sickled" cells can get stuck and clog the blood flow, which can cause severe pain and other serious issues such as infection, acute chest syndrome, and stroke.

Microaggressions?  
They are brief and commonplace daily verbal, behavioral, and environmental indignities that communicate hostile, derogatory, or negative racial insults to the target person or group.
      The physical pain experienced by people with Sickle Cell Disease is only worsened by the microaggressions they have to endure, especially by the hands of medical professionals.

Sickle Hemoglobin - C   Disease (HbSC) is a type of SCD where individuals inherit a sickle cell gene (“S”) from one parent and from the other parent a gene for an abnormal hemoglobin called “C”. This is usually a milder form of SCD.

People who inherit one  sickle cell gene and one normal gene have sickle cell trait (SCT). People with SCT usually do not have any of the symptoms of sickle cell disease (SCD), but they can pass the trait on to their children.
