So I think this is quite strange but I’m gonna post this on hear to see if I can get some ideas/help. Back in 2011 is when I started getting panic attacks/anxiety. One night when all this started for me, I woke up in the middle of a panic attack at which point I was laying on my back. From that point on, I cannot to fall asleep on my back at all but I know sometimes in my sleep I will roll over from my side to my back. Anyways, I think from the constant state of how I sleep on my side all the time is causing me shoulder pain which can cause pain from a 2 to at least a 8 or 9 on the pain scale 10 being the worst whenever I extend my arm underneath my pillow, or move it sometimes. It’s a very sharp pain I would say from the top of my shoulder to close to my bicep. I have a terrible time trying to fall asleep on my back and I wanna try to combat my fear I guess of me falling asleep on my back to see if this helps with my shoulder.

TLDR; Shoulder hurts because of me sleeping on my side I believe. Have had panic attack while sleeping on my back and can’t fall asleep without sleeping on my side.
