Thanks for the reassurances. There are so many moving parts to this disease. My kidney function tests have increased too. I have no idea how kidneys come into play with MGUS.
I will be prepared for my haematologist appointment. He seems to be leaving it up to me to decide if I want the bone marrow biopsy. I'm happy to postpone it for a year or two or until he says We need to do it. This is a long game I think and I have to get used to waiting.
