I am not a doctor, but the way I've handled all injuries for me is to do RICE for at least a week. If it is getting better, stay the course and slowly reintroduce activity as things shore up.
If it's staying the same or getting worse after that week, see a doctor. Of course, if the pain is to the point where it is affecting my daily life, I'd see a doc right away.
I also refrain from asking for medical advice on internet forums.
