Sciatica Sporadica

My sister--my bride, my dear beloved wife is suffering in her current pregnancy. Though I remember that her sporadic bouts of sciatica were just as bad in her previous pregnancies, she's convinced this is the worst it has ever been. The worst part about it is, it only seems to strike when she is the most relaxed. So I pray today for her pain to ease or a remedy arise to ease the stress on her sciatic nerve so that she may have a little comfort.
