The welt bones generally refer to the calf bones, including the tibia and fibula. Running calf bone headache may be caused by incorrect running posture, or it may be caused by the patient himself suffering from bone fracture, osteoporosis and other reasons. 1. Incorrect running posture: it will increase the load on the calf, and the bones of the calf can be shaken, which will trigger bone contusion, and then pain can appear. 2. Bone fracture: It is an incomplete fracture where the bone tissue is cracked but not broken. It may be caused by direct or indirect action of violence, chronic strain, etc. When running, the pressure on the calf increases, and the bone fracture can be stimulated, resulting in pain in the lesion area, redness and swelling of the skin, and other symptoms. 3. Osteoporosis: It is a systemic bone disease characterized by low bone mass and damage to bone microstructure, leading to increased bone fragility and easy fracture. It may be caused by vitamin D deficiency, hyperthyroidism and other reasons. When running, the reaction force of the ground will stimulate the bones of the calf and produce subtle damage, thus causing local pain symptoms. Running calf bone headache can also be seen in other causes, it is recommended to go to the hospital in time, clear cause and follow the doctor’s instructions for treatment, to avoid delaying the condition.
