Shoulder pain at night is a common symptom of shoulder arthritis and contributes to sleep disturbances. Many patients also have difficulty sleeping after shoulder surgery due to the constraints of sling immobilization. While in the hospital, sleep is also disrupted due to pain, nursing staff, other patients, and bathroom use. While poor sleep may appear trivial, sleep deprivation in animal models has identified significant adverse effects on bone metabolism, bone mass, and recovery from post surgical pain.
