pain
"I was given Percocet recently after knee surgery.  After about the 4th dose, I felt hyper, restless, nauseous and had very dry mouth.  Worst side effect was extreme throbbing/stabbing lower back pain.  I thought it was from just laying around but whenever I didn't take the Percocet I didn't have the lower back pain.  Great for pain, but for me it's not worth the side effects I experienced."
