I went to see Dr. Zhang after five frustrating months with the NHS and physiotherapists. I had damaged the medial ligaments in my knees in a freak accident, and was often in considerable pain when walking or even standing still. There months of physiotherapy brought no relief whatsoever. After just three sessions with Dr. Zhang, though, I can walk across town pain free! Still more work to be done on the injury, but there has been incredible improvement in a very short period of time.
