What is a good sleeping position after shoulder dislocation?

Anything Comfortable. You should just listen to your body and sleep in a comfortable position. Your doc and/or physical therapist may have some more specific suggestions depending on the specifics of your injury but comfort is a good guide. (most will find laying on their back with their arm resting on a pillow. Some, who cannot sleep on their back, find using a recliner and pillow to work well.).
Depends. Depends on the type of shoulder dislocation that occurred. It is best to see an orthopaedic surgeon and have them direct you to this.
