I also was prescribed oxycodone from my PMdr for a lower back injury. After 2years I decided that I no longer had to go through the pain of an opiate addiction and an injury. I am currently 17 days with no oxy and everything is starting to get better. I found a new doctor who is trying healthier ways to relieve my pain; mainly through a healthy diet and physical therapy (I never thought that would work - but so far it is). The pain no longer bothers me, all I want is to be free of the opiates. I know you said Phys Therapy didnt work, can try seeing a nutritionist, i swear by it now. _ wish you all the best
