Currently, numbness in the leg is present, which is primarily attributed to sequelae following a previous fracture—most likely resulting from inadequate rehabilitation after the fracture. For now, the main recommendations are regular local heat application and massage as part of supportive therapy. Additionally, blood-activating and stasis-resolving medications may be appropriately used. Daily activities should avoid excessive or strenuous exertion, while maintaining moderate, appropriate movement.
