Hi Debi,
About your Mom's broken ribs. I have been told by many in the radiology field that rib fractures are not always easy to see on x-ray films. It is not unusual to have repeat x-rays.
Hope there are no additional injuries discovered. Your Mom must really be stoic. I could not lay down with my fractured ribs. I had to sleep in a chair for a LONG time. Every breath hurt but breathing was a necessity.
