Thanks for the reply. Yes, those have been checked. It feels like several quarts of blood were drawn, both by my PCP and Hematologist. That is what led to the Bone Marrow Biopsy. Headaches are frequent, along with fatigue. Also have had exposure to lead 40 years ago, those levels are also normal. Hematologist scratching her head.
