I'm sorry,no personal experiences. I know its associated with bone pain, breaks in the ribs and spinal compression. Constant infections, and sometimes pneumonia. It reduces the imune systems ability. There can be anemia, confusion. I think they biopsy the bone marrow to prove diagnisis and then chemo if its confirmed. But there are a lot of variable.
I hope that what ever it is, it works out well for you.
