I'm about 21 weeks now, and am starting to have some hip pain, just in my left hip. I actually had almost the same thing back before I was pregnant and was going to physical therapy for a few visits. Then, though, I thought I'd strained it gardening a lot, but now I really haven't done anything that could cause it. I'm contemplating getting one of those pregnancy body pillow things to see if that helps, since I like to fling my left leg way over while I sleep, which I think could be aggravating it. I have a hard time sleeping with a pillow between my legs I was wondering if anyone had used one of these and if it helped? Also, does it make you too hot? Any recommendations for particular brands/pillows? Thanks!
