Ask the attorney – Feeling the injuries after the fact

Atty Haymond,

My wife was involved in an accident during the heaviest part of the rainstorm Sunday.

She left the scene after exchanging information because she didn't think she was seriously injured and didn't want to hang around in the yucky conditions.

She woke up this morning, was in serious pain and went to the walk in where the doctor says her injuries may require surgery.

What should we do ?
