Post Posterior Lumbar Interbody Fusion with bone graft and screw pedicles I undergo a PLIF at my L5-S1 last July of 2009. After surgery and PT my right leg and right foot pain improved but my back pain remains but not as bad before my surgery. After I was released by my surgeon in Jan of 2010, I started having back pain that I can not tolerate even with medication and it started @ May of 2010. My back pain get worst in time until I started feeling pain on my right leg and foot. So I was forced to go and seek help from my primary doctor. He gave me a medication for my nerve pain and spasms. He also ordered an MRI so when I see my surgeon I already have a new MRI in hand. The MRI result shows joint degenerative disc disease and scar tissue on my surgical site. My question now is, does the scar tissue can be the cause of my right leg pain and foot. Because of unbearable pain my right knee starts hurting as well and now I have to use my walker or my cane since it has gotten worst in time and getting weaker.
