I’m gonna focus on the Title Question. How to mentally overcome sciatic. Take a look at this book “Healing Back Pain: The Mind-Body Connection” https://www.amazon.ca/dp/B000FA5SGG/ref=cm_sw_r_cp_api_Jaj5FbZZW7QYW?_encoding=UTF8&psc=1
This book focuses on the mental aspect of back injury and pain. I had a physical injury that needed surgery but this book helped me deal with my symptoms (pain aspect) for my 2 year wait before surgery.
The answer for me was twofold. The first: rehabilitative pilates. Private sessions twice a week for 10 years. You need to strengthen your core muscles and keep them strong.
Persistent pain in the back like this is also, I hate to say it, often in the mind and the result of stress and fear. Please read Dr. Sarno's "Healing Back Pain: The Mind Body Connection". It was a life-changing book for me. Let me guess: are you a super type A personality? Perfectionist? People-pleaser? Not super in touch with your emotions? Constantly stressed-out? Then you are prone to TMS: tension myofascial syndrome. Read Sarno on how to end your back pain forever just by realizing why it's happening.
It might help. It's helped me out alot.
I suffered from sciatica for several years, and tried so many things to relieve it. I feel for you. Genuinely can get horrific. I'm going to suggest something that I absolutely rejected until I had reached a dead-end and given up hope. My mom of all people sent me this book:
https://www.amazon.com/Healing-Back-Pain-Mind-Body-Connection-ebook/dp/B000FA5SGG/
It basically argues that much of the back pain epidemic is stress related and largely psychosomatic. It's real, but it isn't what we experience. At the very least it made me much more aware of how much stress in my life was closely connected to my sciatica. Literally certain situations, even certain people walking into the room would really floor the pain. I was like "Whatever" and put in on a shelf for a year, until I finally read it. It was the only thing that actually lessened the sciatica. It didn't cure it, but it took it down several notches. So? Maybe think to yourself whether certain life-stress situations have developed around the time of your sciatica. I was deeply unhappy at the time, and didn't really realize it. Of course physical injury can cause sciatica, but the author argues that in the majority of cases the main backpain trick is convincing you that you have a physical injury that more or less can't be cured.
I ended up having a serious traumatic event and the sciatica cleared up immediately after and never came back.
