accupuncture.
my friend who is due is november is also suffering with sciatica and has been seeing a woman who does Chiropractor/accupuncturist/masseuse....
one who specializes in pregnancy is very important.
dont be afraid to see another chiropractor...there are some really great ones out there.
i know how painful it is, im sorry you are struggling.
feel better, and go find a new dr.
