I tried to ask this question a few days ago and I put in all of my drug info and the question disappeared. I don't know why but I need help with this. I have been on Fentanyl for 3 years, The dosages have changed and yes I know I must be tolerant to it. I have been in agony for 2 1/2 months with the pain. Could someone please explain this better to me. The doctor just added benzos and I will not take them because it interacts with other meds and all I want to do is just quit. I would really appreciate any input.
