I HAVE OXYCODNE/ACETIMINOPHEN LEFT OVER FROM A SURGERY A FEW

I HAVE OXYCODNE/ACETIMINOPHEN LEFT OVER FROM A SURGERY A FEW MONTHS AGO, WHICH I USED then FOR PAIN relief. I HAVE BEEN PRESCRIBED DICLOFENAC last week FOR PAIN RELIEF OF MY ROTATOR CUFF TENDONITIS. I pulled a muscle in my back yesterday and I AM IN GREAT PAIN AND THE DICLOFENAC IS NOT WORKING TO REDUCE PAIN ENOUGH FOR ME TO GET A GOOD NIGHT SLEEP. CAN I TAKE THE OXYCODONE TODAY AND TOMORROW ALONG WITH THE DICLOFENAC, UNTIL I CAN SEE MY DOCTOR ON MONDAY
