Physical Therapy: Physical therapy can help rehabilitate the structures surrounding the clavicle after injury to decrease pain, restore range of motion and proper joint mobility, and strengthen the muscles around the shoulders and shoulder blades.For acromioclavicular and sternoclavicular joint sprains or dislocations, you may need to wear a shoulder sling for two to six weeks, depending on the severity of the injury. For a clavicle fracture, you may need to wear a shoulder sling for six to eight weeks until the bone heals. Immobilization: It may be necessary to wear a shoulder sling to protect your clavicle after an injury.Overhead movements and pulling, pushing, and lifting should be avoided. Rest: Avoiding activities that cause increased symptoms for associated conditions of the clavicle is often necessary to allow time for inflammation to decrease and for injured joints to heal.Cortisone injections: Cortisone can be injected into the acromioclavicular joint to help decrease pain and inflammation.Medications: Pain-relieving and anti-inflammatory medications can temporarily be used to manage symptoms after injury.
