My experience is the exact opposite of yours. I was told for 12 years my back pain was caused by bulging discs, having a spine that has a reduced natural curve and also caused by poor posture. I read Sarno's book and I have been pain free since November last year. I have never gone longer than 2 weeks without severe sciatic or SI joint pain.
Please don't dismiss Sarno's work as BS. It may have not been the right fit for you, but it is for countless other people. Sarno's work is aimed at exactly people who don't have a real biomechanical issue like yourself. It's not a one size fits all, nor is Physiotherapy or surgery.
Also in general, Sarno doesn't reccomend journaling to everyone. A simple mindset change works for most people. Worked for me.
