Hi my husband has multiple myeloma and has also been diagnosed with c.o.p.d.Due to this he was refused his stem cell transplant and at the moment is not on any medication.He attends hospital once a month for a zemeeta.He is experiencing a loss of balance sore heads and sickness are these symptoms of his illness.
You said he is only on COMETA now. I presume he is in complete remission. If the disease is in remission, his symptoms cannot be attributed to myeloma. Please don't delay medical attention attributing his symptoms to myeloma. Please consult a neurologist. Good clinical examination will point to the cause of his state and treatment can be offered accordingly
