I am on my second Medtronic pain pump. Every seven years it needs to be replaced, it is a same day procedure. Every discin my back is either herniated or compromised. I've had both front and back cervical C2-C7 operations. My complete lumbar spine was fused with a laminectomy. My left shoulder hip, knee and hip are replaced. About nine years ago I became in operable, and was offered either the stimulator or a morphine pump. I spoke with two women who had the stimulator and tney told me don't waste your money or your time. So i choose the pain pump. With it I can get out of bed in the morning and goo about my daily rountine. It is like getting your life back. Sometimes there is breakthrough pain - if i overdo it or the pain comes from somewhere else, like my shoulder. I can take some meds by mouth ffor that problem.I;m 74 years old and I have to adjust to my condition, which sometimes is hard. All in all, if you have patience and follow the instructions you can feel a lot better.it's better than being knocked out all the time and unable to drive, etc. hope this helps.
