Back pain!

I'm almost 28 weeks and I have the worst back pain. Especially while trying to sleep, I have a pregnancy pillow but it gets to hot and hurts my neck. Sticking a pillow between my legs helps a little though! I also wear a back brace at work because I'm on my feet for about 6 hours a day. Any advice? Because this is very Painful and I have a long way to go! 86 days to be exact! Haha
