Hi Dr. Rynne, I was struck by car two nights ago while walking (ironically, to lose weight and improve my fitness level). I have not been seen in an ER or by a medical professional. The only symptoms immediately after the accident were a sore knee (that feels much better today) and soreness in my left front lower ribs. This symptom worsened considerably overnight. Should I see a doctor? Or is this just that classic rib pain that I ve read so much about that cannot really be treated?
