I am glad your post was bumped as I had missed it, they often take a day to get through the moderator who has to check every new conversation to try and prevent any inapropriate ones.
Your Dad does sound to be quite poorly and the level of pain he is suffering is not good, neither is the high dose of morphine if it is making him hallucinate.
Regrettably there sometimes comes a time when a Man becomes totally resistant to hormone treatments like the 3 monthly injections, tablets like casodex (biculatmide) etc.
Your dad's team may have opted for enzalutamide as it is a much newer type of treatment, he may have been taken off it just temporarily as he is so ill, but more likely (and this is the toughest part) because it is not working for him either.
His pain and poor mobility are probably due to the cancer being quite active and putting out much higher levels of PSA, he may also be having some problems with calcium levels. If he has had a blood transfusion this will be because he has readings of some cell types that are abnormal, like Haemaglobin, red cells or white cells, the transfusion should boost those and improve general well being for a while. They can do these fairy regularly if they help. Has he had any calcium treatments or bone strengthening infusions like Denusomab or Zometa?
You have not said what your Dad's PSA level is now and what it has been previously, this information might be useful to anyone responding to you. Also has your Dad had any chemotherapy at all or has this been mentioned as an option? A combination of age and general strength and well being would impact on the possibility of this.
As for the pain management, some people really do not tolerate morphine or other opiates taken as tablets or even as infusions/injections although they can manage the skin patch varietals like fentanyl which have far fewer side effects. There are so many different pain medications for ll different types of pain (nerve pain, bone pain, muscle pain etc) also they can be given in combinations and in so many different ways that Macmillan and other specialist oncology nurses, hospices and even some medical practices and hospitals have specialists who deal in this.
If you are able to speak to your Dad's GP or the doctors in the hospital ask if your Dad can be referred to the Macmillan pain management team, or your local hospice. The constant pain will not be helping your Dad to deal with things and will have a very significant impact on his quality of life (often referred to as QOL)
You mentioned he had Radiotherapy (RT) was this in his hip to try and reduce any boney mestatases (mets) there? If your Dad has had a recent MRI or CT scan have they shown any spinal mets as these can also cause significant pain and mobility issues as well as general weakness in places like the legs, arms and neck.
I know this all sounds like so much informtion and so many questions but the more we know the more we can try and guide you to the right place and people to get the professional help you need for your Dad.
One thing I would add is that people often balk at the word hospice as they think that is where people go to die. That is not at all true these days, I work in a hospice as a volunteer and we have people who come and go for many different reasons the most common of which are pain management and poor appetite.
If you need someone to chat with off the forum you can always send me a private message through here.
Thankyou for caring so much about your Dad to join us here, having your support will mean so much to him.
Best wishes
