If both tibia as well as fibula have been fractured, one is likely to suffer from severe pain while walking. Tibia is the weight-bearing bone of the lower leg, so one's range of motion gets adversely affected if tibia is fractured. If it is just the fibula that has been fractured, one is likely to experience pain along the outer leg. Pain, swelling, bruising and tenderness at the site of injury are other symptoms that one may experience in event of a fractured fibula.
