I also have the hip one for well my hips and tailbone. I've had it from like 16 weeks.I can't wear it while i'm sitting, however i do wear it when i'm doing housework, at work (cuz i stand all day) and also when i sleep. I can't do the housework or work without it. it's too painful. It was hard to get used to at first but now i find it much more comfortable and it helps stop pain.
