For several years I have had an elevated White Blood Cell count. Sometimes it's normal other times it's very high. I was sent down to a hematologist and he did an extensive blood work up that shows no signs of leukemia or lymphoma. He is thinking my body just reacts to "inflammation" differently and it could be elevated from smoking too much, or having a sore back. To be sure he wants to do a Bone Marrow Biopsy. I had 4 cortisone shots in my back several years ago that went into my bone and I still have soreness from that. I don't know anyone who has ever had a bone marrow biopsy and I'm just wanting some insight on what they experienced.
