My oncologist says that he cannot rule out multiple Myeloma unless I have a bone marrow biopsy.?

So far all of my blood work have been great. The only blood numbers that were off was a high IgE count. However I waited a month and my IgE level is still elevated in the two hundreds but it is lower than a test he found from 2009. I don't want to have the bone marrow biopsy but I do have a lot of pain that comes and goes throughout my body. After investigating this cancer it appears that the pain is consistent and usually does not come and go. However this is a neuropathy connected to this cancer that can cause pain similar to my symptoms. Any thoughts? I am tired of this ordeal and really don't want a BNB.
