Help?

I just started a new job at a preschool last week and the constant moving and bending is starting to make my pelvic area hurt so bad that I can barely walk or bend over at the end of the day. Even showering is a hard time. My husband has started to have to help me to get dressed after ward. Tylenol, warm baths and showers, and resting isn't helping. And since I can't use heating pads or anthi g like that, I'm just wondering if anyone has any ideas as to what I can do to ease the pain. I get 1.5 hour lunch breaks so if it's something I can do during that time, too, that's would be awesome!!!
