Ms. Chen, 52 years old
Before treatment: both knees felt cold; while squatting close to 90 degrees, the knee felt tight, swollen and very painful inside; felt like it was locked so could not continue squatting. At this moment, she could not stand up again.
After two treatments, she can completely squat down; both knees are warm and powerful. She can quickly squat and stand up easily. How excited she is!
