She really should have gone to the ER as soon as he possibly could have. Esp with back and neck pain she could have some nerve damage (just make sure that nothing's going numb it could be bad, i mean fingers and toes too btw)
Generally if you wait til you can go to your family doctor one assumes the pain isn't nearly as bad as it is. Last year I had a car accident and ended up with lower back problems, but since I waited to go in my doc immediately thought it wasn't too bad (seriously...would you go in if it "wasn't that bad?" probably not) so he figured I had bruised/inflamed muscles from the impact put me on antiimflammatories for 2 weeks and nothing. Then he started saying stupid shit (to me yes stupid shit, he blamed my weight, my backpack for school, the way I sleep and anything else that can possibly be blamed, now I'd have put that into thought if it weren't for the fact I had NO back issues til the accident) I pretty much said screw this, I'm not paying copay to hear him say my back's really not fucked up. Fast forward last december, go snowboarding fall end up in the medic room. One EMT is checking my back and he says "you know I don't think your spine is sitting like it should be" and now the only way to make it better is to go to a chiropractor and that's not covered at all by insurance and guess what I have to suffer(one more reason to smoke bud...all the pain goes away!) Moral of the story: if it hurts go in ASAP, never wait it out. I'm 18 and my back is beyond screwed up from one fucking accident. Well not that the snowboarding helped at all but still.
