My mom had a back surgery 4 years ago and since then, she has been experiencing all sort of joint pains since then. This time when she came to Canada to visit me, had a severe knee pain, stopping her from normal daily activities. We visited Dr. Ken 3 times and he did an amazing job finding the root of the pain – her back surgery and stiff muscles around the area. With just 2 set of exercises, he helped my mom manage and address the pain in less than a month. I like to thank Dr. Ken here for his knowledge and help. I definitely recommend Dr. Ken.
