Yes, and at age 73 still in MGUS stages, no real symptoms but a bit of neuropathy in my feet. This expert explains it quite well in her YouTube video if you really want to get into what it is, how it does or does not progress, etc. This doctor is tops in the MGUS/MM field and works at the Dana Farber Cancer in Boston. If you go to YouTube you can find MANY very credible videos that explain in even more detail what MGUS is and the various tests, and symptoms one can get over time, etc.
