I have had consistently low WBC counts (2.2, 2.4, etc.) for several years after diagnosis with CFIDS. I have had a bone marrow biopsy and no cancer or other problems other than it showed that there was some damage to the bone marrow. I have been diagnosed with neutropenia. I have been checked for Lyme disease and other types of infections. Have had EBV and occasional flare ups of of Cpn.
