Is your mattress old? It might not be supporting you like it use to. Try different types of pillows also, those memory foam ones can be too firm.
when i hurt my neck the doctor said to not use a pillow or use a very thin one, and sleep on my back. pretty comfy once you get used to it.
I just bought it last year. Some mattress from ikea https://www.ikea.com/us/en/catalog/products/00272208/
I have two. One for my head and one to pull up next to me under my arm. I sleep facing down though. The arm pillow keeps me slightly on my side. I suppose if I slept on my back I'd only need one.
4 1 memory foam for my head 1 thin pillow between my knees 1 thin pillow under my arm 1 last pillow if any of those previous pillows fail at their job.
I don't mess around. I just had a great nights sleep. I will credit two beers and a whiskey drink for that though.
Dude. Go buy a real good matress. Seriously. You spend a quarter of your life on it. Its as important as good shoes if you ask me, when it comes to comfort.
How old are you? Trust me on this. The older you get the more important you will find having a good bed is. I wish I could go back to my 20's and get a good mattress. I firmly believe I wouldn't have near the back issues I have if I would have taken better care of myself when I was younger. *old man preaching, I know*
DON'T WORRY ABOUT IT. Dunno, Don't feel like dropping 3 grand on a mattress, rather go to hawaii 3 times.
