There are three main reasons for pain in the bone: first, fracture as well as bone fracture, these injuries will lead to small nerve damage at the broken end of the fracture, nerve irritation occurs and leads to pain. In addition, due to local edema, blood leakage will cause local swelling, which will compress the surrounding tissues or peripheral nerves and cause significant pain. Second, bone disease, mainly seen in bone tumor, bone tuberculosis, these tumor masses will produce extrusion of the surrounding tissue, stimulation of peripheral nerves will also appear after the pain. Third, the muscle attachment point of the bone is strained or strained, and the pain will appear when the local injury position is pulled during the activity. In addition, due to the formation of inflammatory edema after local injury, inflammatory exudate will stimulate the peripheral nerves around, will also appear obvious pain.
