Belly Bands?!?!

Elizabeth
This is my first pregnancy, I'm working full time as a flight paramedic, which means 2-3 24 hour shifts a week. Any other active/on your feet working moms-to-be used belly bands? If so, what brand and when? I'm starting to have so lower back/hip pain but I'm only 23 weeks and 4 days, didn't know if it would be helpful or not?
