I was badly injured. My Dr. Prescribed me Fentanyl and Percocet. I used to be on 100mcgh Fentanyl and 10 Percocet per day. I had been cut back severely. First to 4 then 3 then 2 then 1, now she has cut me off and I am left bedridden. She tested my urine 3 times and no opiotes showed up even though I took all of my pills. She suspects me of selling the pills, but I am ABSOLUTELY taking every one. How can they not show up when I am taking them?
