Consistent back pain even post procedure indicate the need for you to learn Yoga. International Yoga Day on 21 June is an opportunity to learn 35 minute package free of cost. Its being organized all over the world. Medicine is not an answer to your problem. I honestly believe physiotherapy vs Yoga, latter will make your vertebral joints more flexible to bring more relief. Hope it will help you.
