Hi, Patty,
Sorry, this is the first time I've checked the board in quite a while. Of course you're scared, honey--this is terrifying at first. It does start to feel normal after a while, though--I've had it for over a year, and have recently notcied that life just took over and I stopped thinking about it so much.
Since you posted, I hope you've gotten some results back that have eased your mind. For the majority of people, MGUS stays MGUS and never turns into anything more than annoyingly regular bloodwork. Please let me know how you're doing, Patty.
Michelle
