With the steroid injections, my pain average went from 7 to 8, down to a 3 to 4. At this time I was prescribed Opana ER
40 mg, one every 12 hours. With the injections, I asked my doctor to put me on the Opana ER 20 mg, so he did, but added one more a day, or 20 mg every eight hours, three a day. Unfortunately, I can only get 3 steroid injections in a row, then have to wait six months before I can get another epidural injection.
