I have just been diagnosed with Smoldering Multiple Myeloma, I don't have any symptoms except fatigue and some back pain (I have had 2 back surgeries for other reasons) so, I don't know if the back pain is related or not. My bone x-rays and scans all are good along with my kidney function being good. Does anyone have any experience with issue, I really wonder how long it takes to go from smoldering to active. My doctor here is not treating me at all - just doing blood tests every 3 months. I am going to get a second opinion from Mayo Clinic too. Any help would be appreciate
