@bilt4pain I was on the fentanyl patch and it all leaked out through my skin so I was in the hospital for 4 days, the doctor removed the fentanyl patch & put me on Morphine oral medication, due to the laws in the State of Florida, after that I had a spinal cord simulator & it helped but not much, I also was on the Morphine instant & extended release which Both were doing nothing so my pain doctor recommended a Intratracheal pain pump, so he referred me to his best friend who does install the Intrathecal pain pump, but I have a high tolerance for morphine so I tried to get them to put hydromorphone from the beginning but they start off with morphine and it just didn't work so I finally just got into the Hydromorphone, I'm sure it will work because I've never been on it before , I didn't think the fitting all would work because I was on it for a while and then it leaked into my system, I have my appendix out and I was in the recovery room can they give me a gram of morphine and a half a gram of fentanyl and it did nothing so I told them to give me Dilaudid and they gave me a gram of Dilaudid and it worked instantly I was out of pain, I certainly hope everything works out for you thanks Michael
