I had a major back operation when i was just 29, every since my surgery I had dealt with back pain. Most days I can deal with it, but I have days like today that i can't handle it and after 4 nagging days I finally went to the ER for the pain and they prescribed this medication to me for it. I am a little curious as to how it will help, when this is typically used for migraines. Any input would be nice. Thanks. i am taking fioricet w/codiene capsules.
