The theory behind a pain pump is that a smaller amount of opiate is used, and since it's directed to the spine, it'll be more effective at treating pain and patients can't abuse it or get "high" from it. The reality is docs make BIG money from the pumps installation, and it's often difficult to get the suckers removed if they cause spread or other problems. I wouldn't undergo this procedure...

If you're close enough to Nashville, there is an experienced RSD doc at Vanderbilt you might want to check out.
