Does anyone have any information about pain pumps?

As a young teenager I fell and injured my lower spine. Finally after years of finding a doctor who really believed I was in severe found out that I no longer had a disk between my L5 & S1. In Aug 2009 I went through the surgery to fuse those two levels together and since have had some relief. However I still deal with chronic pain every day. Just this Monday my pain doctor did the trail for the MyStim implant in my back. The purpose of this is to feel tingling sensations rather than pain. Sadly this trial run did not work and it was a nightmare.
My doctor has since rudely said that I was reaching the point of not being able to be treated. He refuses to prescribe any more pain meds, even though the meds I am on are not a very high dosage. I take tramadol 50mg twice a day. My doctor did say my very last option is a pain pump or a morphine pump. I honestly have never heard of these types of pain pumps.  I will be flat out honest; I am terrified of living the rest of my life in pain. Does anyone know anything about pain pumps, what the general procedure is for it, and ultimately does it work? Any help would be greatly appreciated.  I see my doctor again in 2 days and I would like to be able to go in there as informed as possible.
Thanks, Bobbie

Bobbie-Post your question in pain management. You will get a better response, I think. Going from ultrum to a pain pump sounds like a big jump to me, but there are a lot of people over there with some good experience.
