I have recently been diagnosed with early stage cml and am having severe lower back pain that is so bad i can't get off the floor. is this related?

Could be : Chronic myelogenous leukemia is increased abnormal myeloid and similar stem cells in the bone marrow located in vertebrae and other bones but aside from very high white counts often do not cause back pains. There are complications: tumor outside bones that may rarely occur or even collapsed bony structures leading to pain. Best check with oncologist and do imaging . Good news is Gleevec (imatinib) cures.
