please help my trial SCS only helped about 30% of the pain. Not enough to justify implantation. I have severe mid back pain when walking or standing. I had a Lumbar instrumented fusion 18 months ago. I have DDD at L3-L4. Disc herinatiion at T12-L1. Herniated disc at C7-1. Stenosis at L3-L4. And Lumbar Spondylosis. The pain is debilitating at times and I can't walk a block without having to sit. It feels like a major tightening in my mid back and feels like I have knives stabbing me. Does anyone else suffer from this type of pain?
