I was highly resistant to even the thought of spinal surgery; but after two chiropractors and 3 months of PT with very little as far as results, I needed to do something different. So glad my PT referred me to Dr. Yeung. Treated my lumbar spinal stenosis with an outpatient surgery, lumbar hemilaminotomy. From the day OF surgery, I was free of the bilateral numbness which kept me from walking more than two blocks for the past 6 months. The day after surgery and for the next two weeks, I've been walking 5-6 miles/day with no pain and NO numbness. Cannot recommend him highly enough.
