I ve recently had an MRI of my spine. A little background.........in 2012 I had a fusion done at L4-L5 S-1. I had a complication the days following the . An arterial bleed in the space of the fusion. They went back in, stopped the bleeding and evacuated a blood clot that formed on my L4 nerve. After 1 year they determined my nerve damage was permanent. I ve had numbness on my left side, hip to foot. Recently I ve had new numbness from the bottom of my foot to my heel (the n top of my foot has been numb since surgery). Also, now the top of my thigh is numb too. The MRI revealed the following: L3-4 Partial disc desiccation and diffuse annular bulge. Moderate facet arthropathy and ligamentous flavum hypertrophy. What exactly does that mean??/ Thanks, Lori
