I have severe arthritis in my right knee. The pain has become so excruciating that I could not walk without a limp. After going to several doctors without any relief, I went to see Dr. Tong. After just two visits with him, I was able to walk without a limp, and most of my pain was gone. Two weeks of treatments later, I was 100% well. I highly recommend you to go see Dr. Tong if you have a similar problem.
