I had Ultrasound. The assistant did not help me.She asked me to lift up my painful leg in the air, and hold it for minutes when she checked the back of my knee. I don't know how many times, and how long, but it was too much. After 1 week I have too much pain in my thigh when I am walking, when I am sitting. Before the Ultrasound I didn't have pain in my thigh. She was't helpful, friendly and competent. It was a nightmare. /523 The Queensway, Etobicoke X-Ray and Ultrasound /
