My wife was in a head on collision three weeks ago. She suffered some pretty serious lower leg bruising from the knee air bags. She is finally able to walk with out crutches, however she has developed almost like a large pocket on her inner calf. It almost feels like its filled with blood or something. It really bothers her when she stands. She says it feels like something almost running into it when she stands. Her physician doesn t seem overly concerned however. Should she seek a second opinion?
