Yup. It's horrid. I ended up with a huge tubi-bandage around my hips to keep them together until the tummy popped out (this was about 20-25w - I know it was for three weeks, plus a week of pain before that). I need it again, but I'm too big to fit in it... will be calling the company who make the girdle today to scream at them once I get home because it HURTS.

Go speak to a physiotherapist who can advise you on exercises, sleeping positions and give you a bandage. (And I'm huge with the largest hips ever, so it's just the luck of the draw, I'm afraid!)
