"i have been in terrible lower back pain for over 2 years. after numerous mri&#039;s and other tests and alot of different doctors, nothing showed up that should be causing that much pain. they did find a problem in my l1 disc but nothing major. i have a very high tolerence for pain and could barely function. all the different doctors put me on vicodin 10/325 but it only worked for an hour. the doctors treated me as if i was a drug addict even my pain management doctor. after i took a so called routine drug test, my very next visit after she saw i passed my drug test she put me on opana er 20mg. instantly my back pain was 90% gone. i don&#039;t feel high, just pain free. i forgot what that felt like. my pain level went from a 10 to a 3 instantly."
