hi, thank-you for providing the brief history of you. A thorough clinical neuromuscular assessment is advised. As you have cervical disc and lumbar disc degenerative disc disease, the medicine prescribed in any of the dosage will have a temporary pain relief as majority of medications are for symptomatic relief. Also, no pain management specialist will induce more or high drug to allow the body to enter into side effects. I will recommend you to undergo physical therapy like therapeutic ultrasound therapy and TENS therapy which will have effect on reduction of the pain and the research supports the best of these modalities for pain relief. Also, you need to perform regular exercises to strengthen the muscles of the neck and back to regain the inter vertebral disc space and avoid compression on nerve roots physiologically. In my clinical practice most cases with cervical and lumbar disc degenerative disc disease works well with physical therapy. Regards Jay Indravadan Patel
