Sciatica relief?

Emily
The last couple of weeks I've had absolutely debilitating sciatica pain -- unable to walk or move or roll over without searing pain & tears. This was a part of pregnancy no one warned me about. I've been to the obgyn, physical therapist, chiropractor, massage therapist, acupuncturist... and next to no relief. Anyone found a solution? I'm almost 29 weeks and fearing this is what the rest of pregnancy is going to be like...
