I've had 3 major lumbar surgery's, last one last May?

I am not sure what you can do but I believe that you should trust your doctor . You may be hooked on the Percocet might the problem . Somehow you may have to deal with the pain . After so long the Percocet become an addiction and they don't work anymore . Pain can detected just by your blood pressure level . I hope your pain does go away and you get better soon . Good luck and have a great day
