Resentful night owl here!

I had more or less the same with frozen shoulder Romola - shoulders are such awkward joints when you're lying down. I did find pillows & wedges to support the weight of my arm helped (I'm a side-sleeper). & it took over a year, then improved & the other side started. Physio also really helped, especially to retain some range of movement.

When I had a frozen shoulder some years ago, I would wake up frequently in severe pain. I used to get up, take two Ibuprofens and a tot of brandy, warm up the wheat poultice in the microwave, smoke a cigarette and go back to bed.
It went on for over a year, but I hung on to what my GP told me, which was that frozen shoulders always get better eventually. But it was tough teaching through that year.

I too like the sound of rain 👍

Have you tried listening to rain sounds on YouTube? There’s different ones that run for ten hours. I like ones with thunder in. I sleep nearly upright with four pillows on top of a wedge and a pillow under my knees. I just listen to the rain and imagine I’m in a car or tent somewhere safe and I’m asleep before I know it. Hope this helps.

I have just been to the Physio as I had a painful should., it's caused me so much pain, especially when I was in bed.
I can't remember if I did anything to cause it. Physio said it can just happen, straight away she picked up it was my Rota cuff. She gave me a deep massage around the area, some exercises, advised me to ice x3 a day. So much better, hasn't gone completely but it's only been 3 days but vast improvement.
Think about checking out a Physio, cost private just £45

I had the same problem but it was eased with an NRS bed recliner frame (Boots was the cheapest) and can adjust the height until you’re comfortable.

I take a variety, I’m surprised I don’t rattle. I did try to go back to sleep and managed to lightly doze! But thanks

Do you take pain killers? I think I would to help sleep.
I wake up several times through the night but luckily it's not due to pain.

I hope you get the operation soon.
I waited 3 years for a hip replacement and at last had it at New year.
