Vulvar varices/worsening pelvic pressure???

Anyone else experience these? I'm currently 32 weeks. I am a RN and work 12 hour days standing/walking/lifting people, which I'm sure doesn't help! I have terrible pelvic pressure which is relieved some when sitting, but I don't get to do that much, and overall keeps getting worse. I'm wondering if anyone else suffers from this and if so, are you still working?? Going to the OB in 2 days and will ask more about it.
