I should review this long time ago. I went to around the World seven months ago then went back to New York. At the moment I'm back to Australia to see my son and Dr Wong to follow-up and some other health issues. I went to Luciferous Chinese Medicine Clinic in early 2013 for my right knee problem which was very painful when squatting down and couldn't walk for a reasonable distance. Modern Medicine did help for a short period of time after injection. I saw Dr Wong few times in a month at the beginning, the progress was slow and I was about to gave up, Luckily I decided to give Dr Wong to try little longer, as he is kind and sincere. After four months treatment. I'm able to walk without pain, although there is little when squatting down in a bad weather day. I know the pain will go away after all if I keep on the exercise that Dr Wong advised. By now I'm enjoying my life without keen pain most of the time. Highly recommended to anyone with the same problem worth to try.
