Juvenile Idiopathic Arthritis
Symptoms
The most common symptoms of all forms of juvenile idiopathic arthritis (JIA) include:
- Joint pain and swelling that may come and go but is most often persistent.
- Joint stiffness in the morning.
- Irritability, refusal to walk, or protection or guarding of a joint. You might notice your child limping or avoiding the use of a certain joint.
- Often unpredictable changes in symptoms, from periods with no symptoms (remission) to flare-ups.
Even though pain is a common symptom of JIA, a child may not identify pain as a problem. A child may be unable to describe pain or may become accustomed to the presence of pain.2 The child may be more alarmed by symptoms such as stiffness and may be better able to describe those symptoms. Some researchers believe that some children who have repeated medical procedures that cause pain may be afraid of further doctor visits and more anxious about their illness.3 This could cause them to not express or identify their pain because of fear of medical procedures.
Additional symptoms vary depending upon which type of JIA a child has.
Eye disease usually causes no symptoms before permanent vision loss occurs. For this reason, it is very important for a child with JIA to have eye examinations with an ophthalmologist to detect developing eye damage so that treatment can be started before permanent vision problems occur. If symptoms are present, they can include blurred vision; persistently painful, red eyes; sensitivity to light; and vision loss.
Fever spikes caused by systemic JIA typically reach 39.5°C (103°F) to 41°C (106°F), one to two times daily, with a fall to normal between spikes.
Rash caused by systemic JIA is spotty, flat, and sometimes faint red or pink and may occur with the fever. It may erupt over the torso, face, palms, soles of feet, and armpits. The rash often comes and goes and may appear late in the day or in the early morning. It may also be brought on by warm baths or by rubbing or scratching the skin.
Other conditions with similar symptoms to JIA include growing pains, overuse, injury, bone infection, and certain inflammatory diseases, among others. Many conditions can cause painful, stiff joints in children. Most often, occasional joint pain in children is related to an injury or aggravating factors, such as repetitive overuse in sports activities. JIA is a relatively uncommon cause of these symptoms.
Some children have forms of chronic arthritis that are similar to yet distinct from juvenile idiopathic arthritis. These conditions, called spondyloarthropathies, are not addressed in this topic. Examples of spondyloarthropathies are ankylosing spondylitis, Reiter's syndrome, and psoriatic arthritis.
