What position do you sleep , I can't get comfortable

[Glittersparkle24]

I have been finding it really hard to get comfortable. I like to sleep on my side. But the top of my shoulder ends up hurting and painful then I turn over and it's the same the other side. Then I try sleeping on my stomach for a bit . But then my should is still painful when I try to position it.

I have a memory foam mattress it was 600 so not cheap. Well nlt to me anyway. I have had it around 18 months. I have had the sleep position problem for around 2 weeks. I don't think its the mattress as I hsbe been fine till recently.

Also what can I used to prop myself up in bed. It's just for if I'm reading or something. I don't want to sit fully up . Pillows are not really doing it .

This is like me. Dh said its like a splat position. Like you see in films where someone's fallen and landed on the ground. I read people with hypermobility are the ones who sleep like it mostly
