Sciatic pain

Has anyone else experienced severe sciatic pain in pregnancy? Mines gotten so bad in the last day that I can hardly move. I had to phone in sick at work today because I can’t get out of bed. The pain takes my breath away. Has anybody else had to take sick time for this? I was already out of work for 2 months in the beginning of my pregnancy for morning sickness so I’ve been feeling bad about phoning in.
