Juvenile Arthritis | Symptoms & Causes

What are the symptoms of juvenile arthritis?

The signs and symptoms can vary, depending on what type of juvenile arthritis your child has.

Some of the most common symptoms of juvenile arthritis include swelling of a joint, along with stiffness and pain. Symptoms can involve the hands, feet, and knees, but any joint can be involved. Joint stiffness occurs primarily in the morning or after long periods of inactivity (gelling phenomenon). Other signs include:

  • limping, especially in the morning
  • clumsiness
  • swelling in the lymph nodes
  • high fever
  • skin rash

Symptoms may get better or disappear completely for periods of time (remission), and then flare up at other times.

What are the causes of juvenile arthritis?

The cause of juvenile arthritis is unknown. As with most autoimmune diseases, individual cases of JIA are likely due to a combination of genetic factors, environmental exposures and the child’s immune system.
