Pain
"I just started with Opana ER 5mg every 12 hours. The first time I used it, it did help with the pain, not much but a little. Then after a few days, I started suffering from some of the side effects. Anxiety attacks that verged on the near panic attack stage, difficulty breathing, and a few others. I told my doctor that I have heart problems, asthma, and a history of seizures, but he decided that he would give it to me anyway.  I am glad that Opana ER works for some, but it is not the one for me."
