My doctor sent me to a physical therapist for hip pain. PT diagnosed Piriformis Syndrome. Hip massage brought pain relief. The PT suggested that problem and back pain might be caused by leg length discrepancy. He says my left leg is about 3/8" shorter. Hip pain is left hip, back muscle tightness is on right side, my left shoe wears much more on the left heel. Are these findings consistent? Does the short leg cause more heel wear on shoes? I am trying a heel left on the left foot. I am experiencing some soreness in left leg. Is this adapting to a new situation or something to be concerned about. I am 71 YO male and walk most days between 3 and 5 miles.
