Siatic Nerve HELP

Chey • Nurse and soon to be mom
I wasn't sure where to post this, but has anyone ever experienced problems with their siatic nerve and if so, what helped you to alleviate the pain. I know many women experience problems with it after child birth. I've never given birth, but I have a fairly labor intensive job at a hospital where I'm constantly moving patients for 12 hours a day. It didn't start bothering me too badly until yesterday when I was sitting in class and shifted my weight. I started getting sharp pains. As the day progressed it worsened until I had to avoid moving certain ways. I thought I could go home, go to sleep, and wake up with the pain gone. That was not the case though.
