@jenatsky I had the trial with morphine(did not help) and Dilaudid(helped a lot). This was by injection. So i had the permanent implant with Dilaudid. After two and a half years, I have had ONE DAY of relief. I just went yesterday for a dye test of the pump. Doc says that all is well. Pump is delivering the med to the intrathecal space as it should. So I said, "Why am I not getting any relief"? He was at loss. Said he would present my case at some kind of symposium of his peers. Great! So, I say, what am I to do until then. I'm getting no relief from this thing or may pain meds. He tells me that he doesn't like to prescribe opioids for pain. Wonderful. So, am left to fend for myself. I think that I will try a little weed to see if that helps.
