Thank you Dr. Christopher Yeung! I had a lumbar laminectomy L3 thru L 5 due to spinal stenosis three months ago. I went from walking hunched over to walking upright immediately after my surgery. The numbness and tingling in my right leg was also gone immediately after surgery. I'm a physically fit 65 yr old male. I started walking around the hospital three hours after surgery. Within two weeks I was walking up to five miles per day and at eight weeks I was back on my road bike and riding 45 miles plus at a fast pace. Just had my three month post op checkup and have been cleared to hit the Pickleball courts! I'm back to my physically active life style and am thrilled with the results. Thank you Dr Yeung and staff! I highly recommend!
