Sorry Mike, the MRI pictures are not showing up on the website. Many back surgery's do not work 100%. This is called "failed back surgery", and can be caused by scar tissue formation in the surgical area, or something else causing the problem.
Positive findings on an MRI are not always symptom causers. Your continued low back pain may be due to: scar tissue formation, vitamin deficiency (specifically vitamin D), Sacroiliac joint dysfunction, inflammation of the nerve, piriformis syndrome, etc.
You may want to consider a consultation with a doctor of Chiropractic. Even though you have had a low back surgery you may still benefit from this type of therapy. Good luck!
