Hi I have a 'mystery' injury that has been bothering me for about three weeks. I have pain in my upper thigh, deep. It is exacerbated by walking, jumping, running (which I can't do), etc. I was put on crutches by my doctor. The doctor took x-rays because she suspected a femoral neck stress fracture. The x-ray came back negative, as did the subsequent MRI. The MRI came back negative for EVERYTHING -???? The fulcrum test and single hop test still produces pain....???
