Fell in QC Chin Mansion

Hi all - I may be paranoid but I'm hoping to get some advice.

I was slowly unlatching the top door of my chinchilla mansion & my chin jumped on the lava ledge connected to the door. She must have snuck up there without me realizing as I was grabbing hay (I feel awful) she got startled as the door opened, jumped off and tried to catch her footing on the way down - from what I saw she jumped onto shelves (I have shelves in somewhat of a cyclone around the cage so she was never far from one)...
