Ryn, I had such bad sciatica, that I have been literally unable to move. All i have been able to do is lower to the floor gently and just slowly (very slowly) try and move to ease it up to then crawl to a chair/bed

This happened to me in front of my parents a couple of times and they freaked because I couldn;t move and my dad wanted to help me to a chair and I had to say to just leave me and I will get there in my own time.

I suffer from sciatica and have done all of my life even when I am not pregnant, but when I am pregnant it is much much worse. I have found the only thing that helps me is to have a heat pack (even in summer! ) on my lower back and sit with my legs elevated while the heat takes effect.

I am not sure if this will help, but Ihope it gets better for you.
