Often, only a few of these symptoms are present. When inflammation occurs, chemicals from the body's white blood cells are released into the blood or affected tissues to protect your body from foreign substances. This release of chemicals increases the blood flow to the area of injury or infection, and may result in redness and warmth. Some of the chemicals cause a leak of fluid into the tissues, resulting in swelling. This protective process may stimulate nerves and cause pain.
Inflammation can affect organs as part of an autoimmune disorder.
The type of symptoms depend on which organs are affected. Inflammation of the small tubes that transport air to the lungs may cause an asthma attack. Pain may not be a primary symptom of an inflammatory disease, since many organs do not have many pain-sensitive nerves. Treatment of organ inflammation is directed at the cause of inflammation whenever possible. There are a number of treatment options for inflammatory diseases including medications, rest and exercise, and surgery to correct joint damage.
