Acetaminophen / oxycodone
"I have several chronic back conditions, herniated disc, moderate spinal stenosis, degenerative disc disease and kyphosis.  I have been taking 5/325 mg Percocet 3-4 tabs daily for almost 2 years now.  It relieves probably 80 % of my pain and allows me to function.  Most of the itching, sweating, nausea, etc. disappears after about a month or so of use.  As most people noted, take the minimum strength needed to relieve your pain, and take only as directed.  At 61, I'll probably be on these the rest of my life, but at least I can function.  I have found Percocet to work better than even Morphine, at least in my case.  Highly recommended for chronic pain."
