I am doing much better now,, the awful pain I had in my leg is long gone. Started hormone (Firmagon) one month before starting the chemo. It's not pleasant but definitely doable. I was still working at the time, on my feet and it takes some out of you. For me, being in the bones, I take forever meds. You just have to learn to accept it, so much better then the alternative. Let your dad know he can do this and also one thing I know helped me, my wife was there for all 10 rounds, wouldn't want to go through it by myself. Also for me, it was every 3 weeks, not sure about doing it every week. It's almost 2 years for me and I'm doing good. Make sure he gets to ring the bell.. I wish him and you the best on his journey. Best to all.
