I am now on 20mg of Morphine, 12 hour slow release for about a month and I am in so much pain. I was taken off co-codamol due to high level fatty liver, which has now come down to 92 reading. does anyone take the above and painkillers as the morphine doesn't touch the pain I forgot to mention I take Naproxen 1 in the morning, if I take more I get pains in my stomach. I have RA for 20 years and a prolapse disc and surgery is a possibility. I
have an MRI on Sunday. The surgeon will decide then if I need to have surgery. In the meantime, I am in a lot of pain and working full time. Not a physical job, but still hard to get through the day. I went to see my GP 2 weeks ago he increased the dose from 5mg to 20mg. Does it take a long time for the morphine to take effect?
