Sickle cell answers, with the sources.

Asha does not diagnose or prescribe. She explains the evidence, cites it, and tells you when to get care today.

A patient in pain at midnight, a parent holding a thermometer, a partner who wants to help: this is who arrives here. Between visits they carry a home pain plan and a fever rule that cannot wait until morning. Asha explains the evidence with its sources, and says plainly when it is time to go in.

What patients and families ask

Pain, fever, hydroxyurea and the newer treatments.

Sickle cell disease is lifelong, and most of its care happens at home, between hematology visits. A pain crisis has a home plan and a line where the emergency department takes over. A fever is treated as an emergency because the spleen often stops filtering bacteria early in life.

What does it do, how does the team start and adjust it, and what monitoring goes with it?Ask this Pain crisis, home or ERHow do I tell a sickle cell pain crisis I can manage at home from one that needs the emergency department tonight?

For the people around the patient

Parents learn the fever rule before their child can say the word. Partners and relatives want to help through a crisis without taking it over, and to understand what sickle cell trait means for a family.
