I have been diagnosed with matastic prostate cancer, Still waiting for the various bone scans, mri etc to determine the extent of the metastisis. I have the expected pains including sore back, fevers, chills,etc. I have now developed chest pain (mid chest) both sides that radiates thru to the back just below the shoulder blades. It seems to be related to a foul taste i get in my mouth. (maybe the taste of blood). the taste becomes more foul as i lie on this part of my chest. I did have a chest xray a few weeks ago that came up clear.
