there's just so much pressure on the nerves & everything.. I had sciatica pain something AWFUL too.. oh man, I still can't wait for baby #2 though. worth every bit of pain! (((:
ohhh man, I remember that pain.. my OB just said it was everything getting "prepared for birth" down there. that pain would literally lift me out of my seat sometimes!! especially when I'd sit down in my car.. omg!! it'd even run down into my thigh.. most awful stinging pain ever!!!! it'd literally make me hold my breath..
you're almost there though!!!! congrats & good luck! I delivered at 39w3d! ((:
