I have a medical question on my WIP that I was wondering if you can help me with. I have a 72-year-old woman who falls and hurts her ankle. It swells and throbs and her family brings her to the ER. From my research I gather that she can have a sprain as opposed to a break. I need her to be somewhat mobile because she needs to rush to a caving site where her son is trapped. Is it feasible to think that she can use crutches, can drive, pushing aside that she'll pay a price afterwards? Any suggestions?
