I'm allergic to oxycodone, but I have back and body pains everyday and am afraid to take anything other than alieve. The alieve isn't working anymore?

Xray and pain eval. Oxycodone is not a good medication for you anyway. You will first need xray and full clinical exam to see why you have pains. There are other non-opioid pain meds and you doc may refer home exercise program and other modalities such as ice/heat. www.chrisohmd.com.
See a specialist. See a reputable pain management physician who can help diagnose and treat the underlying condition that is causing your pain, rather than trying to mask it with medications.
