First, decide on the cause of her injury. It could be something simple like a fall while hiking or more dramatic like being caught in a small natural disaster. Then, think about how she reacts to the pain. Does she tough it out or is she more vulnerable? Also, consider the people around her. Who will be there to help? Her friends, family or a stranger? And don't forget to describe the setting well to make the story more vivid.

He would be more hands - on in getting her the help she needs.
