I put this in as a new post rather than as a reply…

When I was first diagnosed I was given morphine for pain. It worked, but it is slow acting and that meant a lot of ups and downs, including at night. My insurance got some reason didn’t cover an oxycodone product so my palliative care team member put me on a low dose fentanyl patch. That was extremely effective and when the time came, I had no trouble getting off by taking one step with even litter dose.

I would ask your PCP or Mayo team for help with pain management. Don’t suffer in silence! And good luck!
