"i have really bad back pain and at such a young age i take percocet 4 times a day and it allows me to sleep and work where as other medications just made my stomach upset.  i would rate it a 9 for the relief it gives you i honestly felt like i could not function anymore i was in so much pain and now i enjoy walking i don&#039;t have to stop ever 10 minutes to catch my breath from my pain."
