Acetaminophen / oxycodone
"I am 23 and have degenerative disc disease, arthritis in my lower back, and two bulging discs. It began when I herniated two discs - L5, S1 and had a discectomy three years ago.  I had relief for about 4 months and then the pain came back.  I am in constant pain now on a daily basis and unfortunately will probably be stuck on meds for the rest of my life.  I have tried many different pain killers and Percocet has been the most beneficial for eliminating my back pain."
