Need answer and suggestions please!

So I am 36 weeks and I’m to that over it point lol. My back hurts 24/7 no matter what, my feet are always swollen even when I have them propped up, I toss and turn all night because I just can’t get comfortable from the aches and pain in my hips, I’m in constant pain in my pelvic area to the point I can barely walk and turn over in bed, and I’m starting to experience slight nausea and headaches (which is something I didn’t experience all pregnancy). Is anybody going through the same thing? If so how are you managing?
