Big legs but bad lower back

[Garza]

Can you all suggest some good leg exercises that will not irritate my lower back as it is always swelling up and causing pain down my sciatic nerve when i do squats or hyper extensions. Also what exercises are good to avoid to help alleviate the problem.
Thanks I think i phrased that bad.

reverse hypers are therapeutic..
placing the bar lower, more on your traps/rear delts may alleviate the pain you get in your low back and sciattica
