Hi. I have been on 7.5mg of Vicoprofen for about 3 months now. I was taking anywhere from 3-5 pills twice a day, sometimes three. My dr. put me on Oxycodone yesterday - 10mg. I took one this morning, and I have felt absolutely no pain relief. I took another about two hours later, and still nothing. Does anyone know why this is? I have never taken anything stronger than hydrocodone before, and from what I understand, this is supposed to be a powerful analgesic (oxycodone). I don't get it!
