What causes inflammation and what are its effects?

ANSWER

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.

The increased number of cells and inflammatory substances within the joint cause irritation, swelling of the joint lining and, eventually, wearing down of cartilage (cushions at the end of bones).
