Taking Oxycodone due to a back surgery gone wrong. I take 3 - 4 pills a day. Usually at night to help with pain and getting sleep but I also take pills as a sleeping aid. When a couple of hours go by and I dont take oxy t i feel like I have a cold. My body aches and I get anxious to the point where I feel I can't breathe. I'm really scared and I dont know if it's me or the oxycodone. Please someone help me I don't know what to do I feel with zero energy. I feel nothing and just doze off everywhere. Please advise..
