Hip and back pain in bed….mattress or aging?!

Hi everyone. I have recently found this sub and been feeling all sorts of relief and pure joy at the posts and comments. Can relate to so many! We are a pretty cool generation with an unmatched sense of humour!

Now, for the last year or so, I’ve been blaming my mattress for causing me so much discomfort in bed. But I’m now curious as to whether it’s actually signs my body is changing (devastating and in denial to a point). I cannot relax and sleep unless my feet are resting and elevated on a small pillow. My hips and back will ache a lot if I don’t have the pillow in place and I will toss and turn all night. Is anyone else noticing aches in bed and has to support themselves? Also open to mattress recommendations! Thanks!
