Terrible back pain!!!

Chrystal
 I've always had sciatic issues but the past few months have been so terribly painful I'm in tears every single day. 27 weeks and 5 days and with my job I'm on my feet for 9-12 hours a day. I've purchased a band that helps lift my belly and support my back but it only helps so much. I'm going to look into a chiropractor to see if that might help me some. I want to work as long as possible and I'm not due until September 1st. Any other suggestions?
