Hello. I haven’t posted in a while. My dad, 89 years old, prostate ca since 1996, stage 4 , lymph nodes only, treated with radiation and casodex. Spread to scapula 2015. Treated with trelstar& radiation. 2018 spread to spine, ribs, femur & skull. Treated with Taxotere. 8/2018 started on Xtandi & his PSA is at 0.8. 1/2019.
He is having severe pain in his neck, back and shoulders. He does have arthritis & bone mets. He is currently on a fentenyl patch 25mcg and takes ES Tylenol He added Advil today & is still hurting. He also is using a lidocaine patch. Could the Xtandi be causing this or cancer progression? Any feedback or suggestions are greatly appreciated. Thank you.
