Sorry To Bother You. We Have A Dr. Appointment For

Sorry to bother you. We have a Dr. appointment for my husband the 26th. He had prostrate cancer in 2008 he had surgery,Chemo, & Radiation. Since then he has been having alot of pain in legs we have contribute it to him being a diabetic. Now he is having a lot of pain in his hip, he cannot even walk up to our mail box with me helping him back. he cant even raise up straight. I know that people say if prostrate cancer spreads it goes to the bone. They have did an xray said nothing was broke or dislocated. I am scare I pane on asking his Dr. to do MRI or Cat scan. Am I being overly caution
