Burn on daughters thigh.

Hello,

My daughter got this burn on her thigh while she was at her grandmothers house. A cup of noodles fell on it when it was very hot still.

The first picture is what they sent me to let me know of the situation and the 2nd picture is now. Should I take her into the ER? It looks like its getting worse. 😩😩😩😩😩😩
