I am a 46 year old female. I have been on pain meds so long and i am very tolerate to them. I have throat cancer. My pain doc has me on 250 mcg' s of fentanly patches every 72 hrs. I am also on morphine 30 mg up to eight times a day, the doc put me on fentora last Tuesday.one of my questions is this, why do you have to disolve fentora in your cheek and you can' t to it under your tongue? I am so afraid to befome addicted to this stuff, that I don' t take it as often as prescribed or I need to. I am in so much pain that I feel suicidal. I am real scared about this stuff. Please help me.
