I had lower back surgery in Oct of 2010 by this surgeon, with fantastic results. He had to "clean out" L-3, top and bottom, of the stenosis. The main nerve trunk line was pinched-off, no circulation, and I was unable to walk. The left thigh, knee, and leg areas were numb. 90 days after the surgery, my leg is returning to its previous point. I am still rehabing by walking, massage theraphy and chiro treatments for the muscles, and sitting in the Jacquazzi for 30 minutes, two times a day. Very happy with the results......
