You've pretty much described my situation except it's my left thigh thats in awful pain. For my lower back and left thigh pain I apply Australian Cream which works very quickly. If the overall pain is too great I take Dilaudid which works almost instantly so be sure you're dad is in bed when he takes it. Get your dad a walking stick , not a cane, It's almost impossible to fall with a walking stick. I used a wheel chair to go to my first visit then used my stick to go the last few feet. Do whatever you need to do to get him the Pluvicto. His bodily function are good, he has an appetite , he hasn't fallen, he's not depressed. Lie if you must but get him into the program. We have no options! They will test his blood and if his bladder and kidneys are ok , he should be good to go. Positive Thinking + family support=success. I'm getting my 4th shot 4/4. My PSA has dropped to 0.38 ! Don't be shy , if you have any questions we are happy to help you. Good Luck , Gene
