Healthline describes bone pain as "extreme tenderness, aching, or other discomfort in one or more bones." Unlike pain in the muscles and joints, patients continue to feel bone pain whether they are stationary or in motion.
MedlinePlus lists several potential causes for bone pain. Overuse, injuries and fractures may lead to bone pain. Bone pain can also be caused when there is cancer in a bone or a metastatic malignant cancer spreads to the bones. Infections, including osteomyelitis, can cause bone pain. An interruption in the blood supply, which is sometimes caused by sickle cell anemia, can also lead to the symptom. Leukemia and osteoporosis are also responsible for causing bone pain.
