I have had MGUS since 2002 - a long time. I no longer get anxious after my semi annual blood draws waiting for my results. I think this could be due to having a different Mayo hematologist (the previous one retired), who seems less anxious about me than my previous one. For 19 years I had blood draws every three months.
My M spike has risen from .4 to 1.3 over these 22 years and my flc have risen dramatically with big bumps after each joint replacement surgery (4).
