Arthritis pain in even one joint can take a toll on your entire body. For example, a painful neck can prevent you from turning your head properly, placing stress on your shoulders. A painful knee may cause you to walk in a way that affects your hips, back and feet. And holding a joint still to protect it can make moving it more difficult and in some cases almost impossible over time. If joint pain is caused by an inflammatory disease such as rheumatoid arthritis or juvenile idiopathic arthritis, systemic treatment is needed to stop inflammation that can lead to joint damage or destruction. For flares of pain, persistent pain or pain due to other causes, there are many things you can do on your own or ask your doctor or physical therapist about to get relief.
