Pain
"I take Opana ER 20mg twice a day along with Oxycodone 30mg 3 times a day for break through pain, I think it works wonderful. I have severe lower back pain all day and all night. If I don&#039;t have the Opana along with the Oxycodone then it just doesn&#039;t work well at all. I have tried many other medicine and this is the one that works for sure."
