Don't be kicking yourself for not taking her to the hospital immediately. There is no way that you could've have known what was happening, and with that tropical storm comming in, who knows what could've happened... could've gotten into a really bad wreck, in which you might be kicking yourself even more now if that happened. You did what everyone else would have done. You annalized the situation, current synopsis didn't indicate an immediate emergency concern (which didn't warrant the need to have your squad to come out and assist - in which case, if it was just a pulled muscle, you probably would've gotten ragged on it by them for quite a while - which might or might not complicate things for you), current conditions to deal with it on your own were poor and a hazard to her's and your safety. Honestly, you did the best thing possible, wait it out untill either conditions to deal with it improved, or if the synopsis of the situation became more clear to what was happening. Unfortunately, the later happened, but you can't control that, and you shouldn't punish yourself for it. You're not a fortune teller, just human like the rest of us. So anyways, I hope she makes it out well. Keep praying for her 'cause she'll need that. Good luck bro, and I hope things turn out for the best.
