Three months after the foot is still painful inside, you can take the following measures: First, such patients should go to the orthopedic department of the hospital above the second level as soon as possible, to clarify the cause of the symptoms, and then to deal with it. For example, in this case, it may suggest that the patient has an old fracture, osteonecrosis, ligament-related injuries. Second, if it is clear that there is an old fracture after consultation, then surgical treatment may be required, such as the need for the fracture site to be reset, coupled with a series of bone grafting and internal fixation of the relevant treatment. Third, if there is clear osteonecrosis, such as talar necrosis, a series of debridement and bone grafting treatments may be required. In some cases, joint fusion may be required. If there is ligament-related damage, it can be treated conservatively with immobilization using a brace for mild cases, while surgical repair is required for severe cases.
