Hiya Jayne,
When I started my treatment I was very ill with a lot of pain and on both sorts of morphine. I found it took a few days to kick in properly and for me to become virtually pain free except when in certain positions.
Don’t worry about becoming addicted to the morphine, take the oral 6 times a day if necessary as well as the slow-release tabs.
If his pain doesn’t decrease a lot within a few days, speak to your team about maybe upping the dose – mine has just been doubled due to a problem with my arm.
Regards
Taff
