Joint pain can affect one or more joints within the body. It most often occurs in the knee, hip, and shoulder, but joint pain may be present anywhere two bones come together.

Joint pain can be caused by many different injuries and conditions, including arthritis, gout, tendinitis, infections, traumatic injuries, and overuse injuries. You should contact a doctor when joint pain lasts longer than three days or if the pain is severe.
