Sciatic Nerve Pain at 31 weeks. Help!

October Momma • 22 year old happily married mother of boy girl twins, Emma and Alden, born 10/11/17😊

Last night I started having really bad sciatic nerve pain and this morning I can hardly walk without shooting pains all the way down from my butt to my ankle. When I lay down I have pulsating pain that just stays there. My question is, does this usually clear up in a few days? Or did it last the rest of your pregnancy? I'll see my doctor on Friday so I figured if it still hurts I'll talk to her then about it. Also, my husband seems to think it will land me on bed rest. I told him that it won't but he's pretty convinced. Did any of you end up on bed rest because of it?
