Sciatica/back pain

What are you expecting mamas doing to help your sciatica or pinching low back pain? I had this issue before getting pregnant occasionally but since becoming pregnant it's a minimum twice a week issue. I can't take hot baths, they make me naseous. I have muscle relaxers that I can take and have cleared them with my dr under the terms "not to make it a habit, but use them cautiously". I've tried the heating pad (on my back only) but that makes it harder for me to get up in the morning. Help please! My husband isn't always around to help me up or do stuff for me.
