My name is BB and I had a PLIF on May 12, 2014 after being in extreme pain since December 2013. After surgery - no pain! Of course I realize I was full of drugs. Before surgery, it was just my legs that were in pain, but now I have a heavy achiness in the lower back area that I didn't have before. From reading posts here, I realize that is normal and also some nerve pain is to be expected. I am happy I had the surgery, I am walking 2-3 miles most days ,exercising in the gym 2 days and swimming several days when I can. I do get the occasional nerve pain but now I know why. Thank you to all of you out there and your informative posts.
