I am having surgery on both Feet for Planter Fascial Fibromatosis, One of my Medications, is Oxycodone- acetaminophen! What can you tell me about this Med, anything to do with Obiou.......? Some New Horrible Drug, Not quite sure of spelling, but something to do with Obyions? I don't know how to spell it? But I would think you would know what I'm trying to ask!? Extremely Additive? Thanks, Donna
