Hi,
I'm a newbie to the site also. I totally know where you coming from with the pain in the shoulders, complete nightmare, i hate it, can sleep, get comfy or anything and cant even lift my son......hate it. Its just starting alot worse in my knees and ankles now, so being able to turn in bed, grab the duvet to cover you is like climbing mount everest.
Hope things get alittle better for you soon
Take Care
