I did a lot of yoga: cat/cow, pigeon, crescent poses helped a lot

Ooh, I had this as well. Ended the minute I delivered, if it makes you feel any better.

Get thee to a chiropractor! He did wonders for my sciatica during pregnancy.

I'm almost 35 weeks w/ lo #2 and think I have sciatica. I have a shooting pain in my right buttock whenever I move in any position but sitting. I've been pretty active this pregnancy and have gained just a bit more weight than the last time (but started out weighing slightly less). Any idea what causes it and how it can be treated? I'm a SAHM of a big 2yo who loves to be carried by me and that makes it even worse. I did some stretches and tried a heating pad, but not much has helped.
