I remember when I was a kid, my late grandma told me that she was scratched by a cat. One of her fingers was blue in colour. The doctor said that she needs to have that finger cut.
My grandma refused. Though, the finger recovered. My younger sister (she is a nurse) complained that doctors need to sit for patient psychology class in order to graduate.
I miss my grandma. Innalillahi wa innalillahi rajiun…Al Fatihah.
