In the hospital again

Hello everyone, this is Dena Jonlaco's wife and I need some encouraging information.  Jon is in the hospital, admitted today, low grade fever, left leg getting weaker and much pain.  Onc admitted him today for an MRI to find out what is causing the pain and weakness.  Jon did have surgery Sept. 30, 2015 to L3 for tumor removal and a plate put there between L2 and L4.  December tumor was back and L3 was radiated which gave Jon some relief for a while, but here we are April and it appears tumor is causing more pain and weakness again.  We won't know exactly what is happening until the MRI is done and reviewed by onc.  Has anyone out there experienced spine issues, surgery and tumor growth?  L3 was Jon's first bone met back in 2013 when he was diagnosed, radiation doc radiated L3 first and then 44 treatments on prostate.  All was under control with L3 until Sept 2015, Dec. 2015.  Jon was going to begin Xofigo and Zytiga after consulting with Dr. Quinn at USC, but this has not happened yet and seems it will be delayed until this issue is taken care of.  I would love to hear anyone's own experiences.  Jon is a Gleason 9 and you can check out his profile.
