Yes, I am past that half century mark as well, and try to stay active, but one Dr., tells me MGUS will cause neuropathy to get worse and I won't be able to walk again, and I read on here some of the people going through MGUS, it is just numbness and no pain and another person will say, there Dr. says neuropathy isn't caused by MGUS, and then some say they got it in the military and like myself, I'm not a veteran! So allot of questions remain unanswered. I absolutely find this forum extremely helpful and enlightning!!
