Answer: D - Repeated trauma to a bone region can result in a stress fracture; this can occur in distance runners and athletes and in individuals with low bone bass (osteoporosis). However, stress fractures do not typically result in severe muscle weakness, unless the pain is so great that it produces weakness. Some of the signs of a stress fracture include: progressive pain that is worse with weight-bearing activity, focal pain, and pain at rest.
