@georgiagurl The BMB results mean a lot. Good luck.

You mention seeing a hematologist - if the physician you are seeing is not a hematologist/oncologist with considerable experience treating monoclonal gammopathies, you should find one. A general-practice hematologist may see only a handful of MG patients in a given year.

By the way, as you may well know, a BMB need not be traumatic. As I wrote above, I (age 74) have had three in the last 18 months. All were performed in hem/onc's office, only with local anesthetic (i.e., no sedation), and none were a big deal. Vibration, pressure, minimal pain. Just don't think about what they're doing.
