I had bad sciata pain for like 4 weeks (it magically went away after i went to the physio), but the advice above is pretty good - especially about sleeping with a pillow between your knees.
If you are looking into private physio, i can recommend a great lady in Caulfield. She specially does pregnant women, whereas a lot of other physios aren't so up on everything that can be done as they mainly do sport injuries. Anyway, i only had o go once, and it was $60 i think.
