Good morning Free spirit.
I was diagnosed IgM Kappa in 2012. I was stable until 2023 when my FLC ratio became abnormal, I developed an m spike which was not before seen on electrophoresis and protein in my urine was found to be mildly elevated. Most recently my small fiber neuropathy has progressed. Still MGUS, although I am seeing a progression. I had a BMB and fat pad biopsy, both which were normal. I am watched closely for a disease called amyloidosis which can be seen in MGUS. All the best on your MGUS journey. Stability is the key!
