Hello, I have not posted any message for a while, but are always learning from all of you. I have found this site very useful. I have some questions about some past tests . I am the one that has IgG Lambda mgus and ACQUIRED von willebrand. I still have had many symptoms which maybe one of you could help explain. My bone survey showed osteopenia and tiny lytic lesion in the back of my skull. Does the osteopenia give you bone pain? Also, I am always getting day and night sweats, had been bad the last couple of days, but have had them off and one since the diagnoses. Also, my blood work was stable except for elevated alpha-1 and elevated alkaline phosphate. Borderline hypercalciumia. But did not run the proper blood test to check my IgG levels, just checked the m-spike. Thank you for any info you can give me
