XP from 2nd Tri- Terrible Sciatica Pain

SnowPea25

Seeing as I am just about to join 3rd tri I thought some of you ladies would have some good remedies as well... 

Sciatica- anyone else? I had this pain with my DS but not nearly this intense, and it went away on its own relatively quickly.

This little lady is resting more on my left, and after sitting or lying down for a while it is like a knife being stabbed into my left butt cheek. It is rough. Here is the kicker- I am supposed to lay down on my left side as much as I can to be proactive in keeping repeat pre-eclampsia at bay...so its unavoidable to be in a position that does not aggravate it.

I went for a prenatal massage yesterday, and was so excited thinking that it would help...and while it felt amazing at the time, afterwards it has seemed to make it worse. I think I am going to try a heating pad today, but does anyone have any suggestions or treatments that has worked for them?
