For months I was limping around with severe pain in my left knee. Doctor said the knee needed replacing and I was put on the surgery waiting list. A friend said I should maybe try William, that maybe he could help and I’m glad I did. William treated my thigh muscles (they had painful trigger points). My knee pain was gone by the next day and did not return. After several months of having no pain, I told my doctor that I would NOT be having the knee replacement done. Four years have passed since the treatment and still no knee pain. I’d recommend to anyone who has been told they need joint replacement to see William first. Perhaps it’s a muscle problem.
