Oh, it's good news that they found the reason for her illness.

Jaundice does make people look strange. My oldest had a touch of it when she was born (not uncommon in infants) and she simply looked tanned.

But your mother going all yellow... no wonder you worry! It's great that you got her those painkillers. Older people are often too 'polite' to ask for what they need.

Now don't forget to take good care of yourself (if not for other reasons then because your mother needs you to be strong right now).
