Hello And I Hope You Can Help Me. I Am

Hello and I hope you can help me. I am a 52 year old female. I had an accident at my workplace, at the age of 27. I have had 2 disk's fused in my neck and neither fused property. I was compensation for 8 months and went back as lightdutywork only. I didn't have my first surgery until 94 and again in 95. Then at a different job as a sa!es clerk, i sold jewelry for 3 years And my lower back L45 was herniated and had to have surgery again in 2014..now here we are 2016 and my MRI stated I have a buldging disc at L5/ S1, and need surgery again!! All of these years from1991 Until present day I have been on pain meds,and xanax. I had a pee test and blood work to check that they are in my systen, and positive also for pot. That does help at times. Can a Dr discontinus all of my meds I've been on for 25 years??!!
