A Jamaican woman living overseas has injected more than $1 million into a medical fund for Mischah Hamilton, a special-needs mother battling avascular necrosis (AVN), brought on by sickle cell disease.

The money – donated by Ka-el Geewax, a special-needs mother herself living in Singapore – is to cover the cost of Hamilton’s hip surgery, scheduled for the end of June.

A common but devastating complication of sickle cell, AVN is the death of bone tissue due to a loss of blood supply, causing the bone to weaken and potentially collapse, most commonly affecting the hip, knee, shoulder, or ankle.
