The symptoms of multiple myeloma are not particularly obvious in the early stage, but may be localized pain, often concentrated in the lumbosacral region, and pain in the thorax and extremities, and sometimes anemia. Multiple myeloma is often associated with osteolytic damage, hypercalcemia, anemia, and kidney damage, so it is recommended to go to a regular hospital for treatment. For patients with multiple myeloma, chemotherapy and immunotherapy are generally used to achieve good results.
