Bone metastases that are severe and serious should not be walked on. Bone metastasis to the lower limbs or spinal bones may lead to severe pain in walking activities and easily lead to pathologic fracture, therefore, it is not suitable to get out of bed to walk in these parts of the bone metastasis. Bone metastasis is a disease mainly manifested by bone damage and pain caused by hematogenous metastasis of certain malignant tumors originating outside the bone tissues to the bone tissues. When bone metastasis occurs in the lower limbs or spine, it will lead to severe pain symptoms, and pathological fracture will be easily caused by insisting on walking. When bone metastasis occurs, the main methods of local treatment are surgery and radiotherapy. Surgery can effectively reduce the tumor load, alleviate the preoperative symptoms, stabilize the bone structure, and relieve the compression of spinal cord and nerves caused by spinal metastatic tumors. Secondly, chemotherapy, targeted therapy and immunotherapy can be used to control the tumor systemically. People with bone metastases need to avoid strenuous exercise in order to prevent pathological fracture, seek medical treatment in time once physical discomfort occurs, relax their mentality, and cooperate with doctors for active treatment, so as to avoid delaying the condition.
