Actually it freaking hurts now. I sit a lot at work, then was taking a course this weekend and did more sitting, and just came back from an event where I had to start standing mid-way through because my tailbone felt like it was on fire. This didn't happen to me pre-pregnancy because I did all these things and maybe sometimes my butt would fall asleep but not this! It's like a fire in my lower back! Ugh! My god! Anyone else experiencing this? I even get it if I sit for just a few hours, even with a pillow behind me and even getting up many times an hour.
