26 year old female - I am confused because I have high levels of IgG protein in my blood (1843)... Gamma Globulin (1.7), M-spike (0.7). I was tested for multiple myeloma (bone marrow biopsy and full body bone scan) because of the above symptoms (bone pain and IgG, and m-spike). The m-spike is supposed to indicate myeloma but the full body x-ray scan showed no lesions or fractures. I don't understand why I would have something that indicates cancer, but yet nothing has been found. Should we look at something else? I know that most of my symptoms are related to iron deficiency anemia but I am still concerned about what is showing up in my blood work.
