This often starts at the age of 2 or 3. The problem is limited to 4 or fewer joints which become swollen and painful. Sometimes the eyes are affected. This affects 5 or more joints. It can start at any age, from a few months onwards, and usually spreads from 1 joint to another quite quickly.
Children often feel generally unwell, sometimes with a fever.
The weather does not cause rheumatic disease, and will not affect how it develops. Many people with arthritis feel that their condition becomes more painful in cold and damp weather. Research has shown no definite link, but there are indications that the pressure changes in the atmosphere may affect our joints. We also know that warmth can release muscle tension and ease pain. So people may feel the effect when it turns cold.
