How does an Opiod-tolerant patient get pain refief?

Im suffering from severe back pain and paralysis of my left hand and other similar symptoms, from an injury at work. I am also almost completely opiod-tolerant, I lack the opiate receptors due to a birth deffect. I've been placed on many different narcotics from Vicodin to Oxycontin and I have limited ir zero relief. I'm an EMT on a medic unit with the County Fire dept here, so I have some medical background. I was sent to a pain "specialist" who was completely useless. He lectured me about the dangers and then tried to convince me that there is a new painkiller that really works, it's called "Acetominophen". When I asked him why he thought that tylenol would work he got very flustered and just mumbled for a bit. Anyway, how do I get relief when I'm so tolerant that nothing works? I am mindful of addiction, every week I go over 24 hours and just take NSAIDS for acute pain to make sure i have no behavioral patterns of addiction or suffer withdrawls.
