LONDON — Victoria Gray had come to Nashville, Tenn., from her home in Mississippi for what was supposed to be a routine checkup. But when a pain crisis struck — an agonizing emergency of sickle cell disease in which Gray’s misshapen red blood cells caught in her blood vessels — the visit became a days-long hospital stay.
