Hi, dear I have gone through your question. I can understand your concern. He has multiple myeloma. His creatinine level is increased suggest kidney failure due to multiple myeloma. Hs hemoglobin is very low. So it is late stage disease with poor prognosis. Treatment of choice is lenolemide plus dexamethasone. Or bortezomib is useful in some cases. Definite treatment is bone marrow transplantation. Consult your doctor and take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using health care magic. Wish you a very good health.
