I would think the doctor would at least have him come in once a year.. My levels have been down but I only go every 6 months but Im still kinda new with this MGUS. I have a lot of pain but I was told that its not MGUS Fibromyalgia, but I was never really tested for it but I'm on Pregabalin 3x a day at 100mg which helps some but not for long I notice it only helps with some pain in my hands . I have been having tingling in my fingers and feels like fingers are asleep and on fire I get woke up from a dead sleep because I can feel it in my fingers but I really fill that its from my back pain. I would talk to the doctor about the levels being low now for 3 yrs and would like to see about coming less offen. Please let us know how things are going?
