I've had my own problems with pains here and there, and I will say they only get worse with time. You should probably let her know about it. I also may recommend using something like BenGay at night (Only at night cause the stuff stinks! but that seems to help me when I need it - I use this as an alternative until I can get to a doctor)
The longer you let it go, the more it will hurt, and probably be worse to fix. Well, I hope that gives you an idea of how to handle it.
