I've been on oxycodone for about 3 years. I've had two foot surgeries and each time the pain comes back worse. Since I favor my foot I walk funny and my back goes out at least once a month and I'm stuck in bed. My doctor told me when that happens to take 2 of my meds. I do that only when I'm in uncontrollable pain. Since my doctor retired the new doctor taking his place won't refill the medication. I only a a few pills left. I took two yesterday and one today. I'm really shaking today and don't feel that great. Can you go through withdrawals when you only take what doctor has prescribed? What about the pain? What do I do?
