If you sustain a fall onto the shoulder and have pain and decreased motion, you should see a doctor. This is also true if you notice a bump or swelling over the AC joint at the top of the shoulder. If you have ongoing pain in this area that doesn’t improve with rest, ice, and over-the-counter pain medication, it should be evaluated.
