I had PLIF this past February after nearly 10 years of pain. The first 2 years was comprised of working with various doctors and specialists trying to diagnose my pain with virtually no answers. It was found that I had one leg substantially longer than the other. I spent several months in physical therapy to fix a pelvis that was tilted, thought to be because of my leg issue. PT didnt seem to help much and after more visits to more doctors, I was told that they could not find the source of my pain. Fast forward about 5 years, my pain changed substantially, moving from the right to the left leg. I took this opportunity to revisit finding the cause. Now I was living in a new state and a fresh approach seemed like a good thing. After approximately 6 months of visiting a ortho, I was referred to a back surgeon and the rest is history. It took one xray and visit to the surgeon to find out that my pain dating back nearly 8 years was due to a very out of whack spine. In Feb 2011 I had multilevel PLIF (L3-4-5-S1). I couldnt be happier since the surgery. It hasnt been easy but I would do it again in a second if I had to relieve the past year.
