Hi, I am 40 yrs old and my left leg is shorter than the right. So once I got a small lift in my shoe about 4 yrs ago and a physical therapist realigned me. I have not had trouble with my sciatica unless I turn the wrong way or don't wear my lift. The slighest different in your limbs can make a big difference. Carrying children on your hip is not good either. I wish you lots of luck. If your Dr doesn't refer you to a good physical therapist then look for a new Dr.
