Hi Krystal
I am in a similar situation with pain with my Multiple Myeloma. I have had chronic pain for a couple of years now and have been under the care of the palliative care team but at home. I have morphine liquid, methadone, oxycontin and oxynorm and these have helped to reduce the pain. Unfortunately the pain never goes completely but self medication does help.
I have been in hospital several times for pain and they hook you up to morphine and ketamine and it destroys your mind. I would rather be at home surrounded by things and people I know than in a noisy sterile ward.
It all depends how bad your dad is. If he can still function at times when the pain is "under control" then being home is better for him. It is harder for you and your family though but it is more important that your dad is as happy as possible. After all, he is the one with the pain!
For me, being in hospital will be the last resort and even then, I would rather die at home surrounded by my family and dog. Everyone is different.
Talk to your dad and see what he wants to do. No one can force him into pall care. It's what he wants to do and what he is capable of doing at home.
Good luck Krystal. He is lucky to have someone who cares about him as much as you do.
