You don't mention your gender but if you are a female, you may have what I was just diagnosed with. A pelvic upslip which puts your whole body out of wack. I have severe lower back, hip and leg pain. Physical therapy keeps putting it back in place but my muscles aren't strong enough to keep it there. It slips back out with twisting and reaching.I just found a chirpractor who is familiar with this and I am going to go and see if he can help. It really made a difference when it was back in place. I rode to Florida in a car and wasn't crippled when I got there. Good luck.
