You can look back and catch up with my story, but I think I’ve hit a new phase. Prostate cancer spread to a node on left lung. Started back on Xtandi and Lupron. I have pain across my chest at the breast level, under my arms to the upper back. It feels as if my muscles ( what’s left of them) are falling off my bones. I’m not having a heart attack and achey pain is consistent. Has anyone else had anything similar as the cancer spreads to your bones and lungs?
