I attend a Pain Clinic for Fibromyalgia and pain from 4 surgeries on my right shoulder. I have constant, bad pain, and allowed to have only 4, 10mg of oxycodone per day. At my last visit my physician asked me if I d like to try Phoenix F.A.S.T, a fast acting, sublingual Tablet. Can you tell me what this is and if it is supposed to alleviate pain. Thanks, Gwyn
