Useful skill to learn?

I sleep on my stomach, more rarely on the side, but can’t do it on my back. The two times I had broken ribs and this time, following my recent ski fall on my shoulder, sleeping has been a major challenge, because I find myself totally incapable of sleeping on my back. 

I’ve tried many time without success and this is a skill that I’d love to master. Sure positioning one’s self on the stomach can help the airways stay open to reduce snoring and alleviate mild apnea, but there are many good other reasons to sleep on one’s back. 

Sleep specialists say that sleeping on the side or back is considered more beneficial than sleeping on the stomach like I do. In either of these sleep positions, it's easier to keep the spine supported and balanced; this relieves pressure on the spinal tissues and enables the muscles to relax and rest. 

Sleeping on one’s back also alleviates lower back pain and it would make my sleeping on an airplane seat a lot easier during long-haul or night flights, so it makes that skill even more endearing and very worth learning? 

Who know? I might get serious about doing it!
