I have been suffering with low back pain since 2009. It would go away after PT and resurface after few months. It started again this January and in May my pain started to radiate down my left leg. GP, neurologist confirmed disc herniation pinching the sciatic nerve. MRI is scheduled in November. Searching google I came across Healing Back Pain Mind-Body connection by Dr. John Sarno. My pain reduced a lot after reading this book last week. I am convinced I have TMS. I read Day 1 of SEP and joined this forum with a determination to cure myself. Strange thing happened before reading the Day 1. Pain on my left side is getting better however Right side of my back now hurts and I feel my hamstring on the right is tight. I am little scared as this is exactly how pain started on my left side. Is this TMS symptom, how do I stop thinking about this and overcome this fear?
