Stress causes chronic inflammation in the body, which is a prime suspect for causing joint and muscle pain. Inflammation caused by chronic stress may also result in skin conditions such as psoriasis. Quite literally, the stress an individual feels may show up on their skin and can be felt in their joints. It is very important to find healthy outlets for controlling stress so it does not create an acidic environment in the body in which disease and inflammation have free reign. Some examples of activities that will help reduce or eliminate stress include yoga, meditation, reading, writing in a journal, listening to muscle, going for a walk or run, and exercising.
