I had lumbar surgery with Dr. Sahai six months ago. I was in terrible pain and three of my lumbar vertebrae had collapsed. I am happy to say that I am 100% better, pain free and back to normal activities including pilates and I even signed up for my first 5k marathon this September. I attribute this to the excellent surgery and follow up. The most important thing to do, is to move right after the surgery and and do the physical therapy. I am 67 YO and I feel like a new woman!
