Millions of Americans suffer from chronic pain. In fact, chronic pain is one of the most expensive conditions to treat because not only are there surgical bills, but also bills for physical therapy and pain killers. Shoulder pain is another form of chronic and acute pain that can be excruciating and limiting. However, if you are experiencing extreme pain in your shoulder, it can be hard to know if you should get help – some pain can be treated with a little ice. Yet, if the pain is too extreme or if you are noticing a number of other signs, it may be time to head to your emergency room.
