I had similar surgery but a triple laminectomy to pull it out of my spinal cord and then a fusion of all three. I am 15 weeks out and have noticed a stinging, stabbing and burning sensation in the area recently that wasn't there before. I'm using heat packs that seem to be helping and still not doing a lot of lifting and resting in bed about every 2 hours. He said it may take a year before we know what damage is permanent. Maybe try heat and rest along with Advil
