Fractures that are still painful after six months may be caused by incomplete healing of the fracture, bone infection or insufficient exercise. 1. The fracture site is not completely healed, there are still obvious fracture lines will cause pain, especially the tibia middle and lower third of the fracture, femoral neck fracture, talus fracture, navicular fracture, etc., these parts of the fracture healing is slower, and prone to bone non-connections, resulting in long-term pain and discomfort, especially can’t bear weight. 2. Local incision infection or osteomyelitis lesions, especially for open fracture is prone to low-toxicity infection or even osteomyelitis lesions in the late stage, resulting in localized pain, which is generally characterized by poor wound healing or local oozing, redness, swelling and other manifestations. 3. The patient’s own exercise is not enough to cause local muscle atrophy or joint stiffness causing local pain, then need to strengthen the functional exercise. If you have the above symptoms, you should go to the hospital in time, under the guidance of the doctor standardized treatment.
