I felt very comfortable with Dr Nguyen from the very start. She explained my process in detail and answered every question I had going into the procedure. The day of my procedure went very easy and quick. Within 24hrs I am pretty much pain free. Which is a huge difference going from being in the ER with unbearable pain in lower back due to L3,4&5 bulging disk. Shooting pain down my left leg and unable to walk without the help of a cane. I would highly recommend Dr Nguyen to anyone having lower lumbar or sciatica pain for relief before seeking actual back surgery like most back specialist recommend.
