I had a 1 level ACDF @ c3/c4 13 days ago & my doctor told me to wear my hard collar at all times while out of bed, but that I didn't have to wear it while I'm sleeping. Well I've been sleeping with it up until now for stability on advice from several people that have gone through this before. But I still have really bad shoulder pain & realized that may be the cause. So thought I would try sleeping w/o the brace. However I have a really hard time sleeping on my back & was just wondering how dangerous it would be if I rolled over in my sleep & ended up on my side this early in my recovery?
