I was also diagnosed with MGUS in 2019. My primary Dr referred me to a kidney Dr who in turn referred me to a Hematology DR due to high protein levels in my urine. I did the whole bone marrow test full skeletal scan. I was seeing my Dr every 3-4 months now its every 6-9 months. And of course, my diabetic Dr and kidney Dr every 3-4 months. And my hematology Dr explained my results to where i understood what was going on, so grateful for him. My progression on my MGUS is very slow numbers barely rising if at that.
