I don't know if I can add much to the great advice given so far, but wanted to welcome you to the group. Other meds that may be of use if you haven't tried them, are Topamax and Cymbalta.
Are cortisone injections an option?
Definitely look into stretches - sciatica stretch as Tina said, or 'piriformis stretch'.
