I had a similar situation in 2018. I had smoldering myeloma. I started treatment with Revlimid and Dexamethasone. Even with that regimen my numbers went up. I started on Daratumumab a year later. I kept my numbers in acceptable levels for 4years. I then went for a stem cell transplant last spring. My myeloma is in remission. I have never had CRAB symptoms. I am glad I did what I did .
