Always had one leg longer than the other, past year ball of my foot on shorter leg increasingly more pain now arch pain and big toe numb. no injury?

LLD: A limb length discrepancy causes each foot to function different from the other; both abnormally. At 29, the long-standing LLD has finally become apparent. I personally like a scanogram to determine the exact difference; it gets right down to millimeters. After that, some type of orthotic device to accommodate the LLD. Maybe some back x-rays, to check for any compensation higher up.
