i have basically run the gamut of opiods from doctors and pain clinics - legally of course - my doctor and i are very frustrated at this point - she is starting me on opana 10 mg tomorrow - i have barely even heard of opana - problem is i have been on so many things through the years for my chronic pain i am thinking this isnt going to work either - i am 46 and have been on prescribed pain medication forever - is this medication worth a shot - what is it likened to--- thank you
