Hello friends, I am headed back to UC San Francisco to get surgery as well a biopsy of nerves and muscle. Well recently my neurologist sent me a letter saying I need an xray called a skeletal survey to look at my bones also another letter saying I have monocional gammopathy, so I will either be going back to UCSF or Stanford to continue with test. I get these letters from my neurologist with no explanation? Does anyone know why a doc would order these test and what the bone survey and monoclonal gammopathy are? I appreciate all.. thank you... pamee
