I am in the late stages of prostate cancer, which has now metastasized into advanced secondary bone cancer.

I've recently noticed spontaneous, severe, bruising, around many of my bones, (ribs, pelvis, etc.). These bruises also have lumps, and these areas are moderately painful to the touch. I've read this could be due to anemia or compromised platelet levels, but my doctor did not mention these things as possible symptoms..., has anyone else had this happen, and/or been provided with possible reasons/helpful advise, for this type of swelling and bruising?

These new symptoms have been relatively sudden and the bone scan indicates cancer cells in almost every region, including the skull, ribs, spine, pelvis, etc.
