Should I go see a doctor or no? My right leg always grew faster then left and I really do suspect that my right femur is slightly shorter than my left. I measured the difference with my knees bent and my left femur is around 1.5-2cm longer than my right. I usually hear about people going to the doc because of pain, but I have no pain whatsoever. I have hurt my back from squats before, but that was due to lower back slightly rounding. Also, I have no crooked bar when squatting. One would assume that the bar would slightly tilt if one leg was shorter than the other, right? 1:52 is where I can see a leg length difference using that method.
