I fell on my shoulder. The bone is protruding up. Mild offset of the AC joint by 0.9cm seen on XR. What is the typical treatment? Hurts to move

AC Separation. This is a low grade, grade 2 shoulder separation. Treatment is shoulder sling, ice 20 minutes 4 times per day, pain control, full exam by Orthopaedic Surgeon to rule out other injuries, and Physical Therapy.
