Sight from that eye was almost gone, obscured by my cheek. I guess the pressure from sleeping on that slide caused the swelling. I had done a my best to follow the doctor’s orders but I have a hard time sleeping on my back.
It wasn’t until a year later that I figured out how to sleep on my back. I still prefer sleeping on my side, but if I ever need to again, I know how. For anyone else, do this: place a pillow under the hip of the side you sleep on, or sleep on a couch with the back of it next to that side. This will feel more natural to you, as though you were on your side.
I hope that helps someone, it would have been a life saver.
