I am an 80yo woman with ailments that pretty much mirrored yours. I also have digestive issues that made decide there must be a better way. I was on morphine for 8 years 4 times per day. I wanted to get that out of my stomach and liver so I pursued the pump. I am at one month now and woke up on the table 100% pain free. Recovery is 6 to 8 weeks, but aside from that, I feel like a new woman. A tiny fraction of morphine delivered straight to your pain center in the brain rather than 15 mg 4 times a day is brilliant. Wouldn't change a thing!
