I have a question regarding Percocet and addiction. I have been taking Percocet/Tylenol 10MG/650MG pills for about ten months for various pain problems. I have back pain, migraines, joint pains. Nothing over the counter helps and I tried Ultram and it did nothing. I take, on average, 2 pills a day but some days only one or none. I do admit I take them sometimes just to feel relaxed and not always for pain. I am in quite a bit of pain but not always. I have stopped percocet for days at a time with really no withdrawal problems.However, If I do not take it for three or more days my pain is real bad and I also experience mood swings and anxiety problems. How do I know if I am addicted or if I need this medicine. I am confused and concerned.
