Ive worked in an ER for 10 years. We have numerous people come in daily for low back, hip , pelvic pain etc. not once ever has a doctor checked to see if their leg length s are equal. In fact, i referenced my text book for this; my freshman year entry level nursing anatomy text book says human leg lengths can be up to 3/4 of an inch difference and is to be considered normal in treatment plans. Whats the deal?
