Help... Please. I put lotion on my legs today and went to stand up and have been in excruciating pain ever since. I did talk to my nurse, she said it's sciatica. With my 3 other kids, I only had problems in my left hip with a sciatic nerve. This time is completely different. I'm miserable and can barely move. It's in the middle of my lower back and radiating to my hips and down my legs. I need some relief. I was told what to do about it by my nurse, but I want to hear from other moms what you did to relieve the pain. Warm bath, heating pad, Tylenol, ice, stretching... And then??

I'm hitting my 3rd trimester Sunday.
