Juvenile arthritis: symptoms, types, treatment and which doctor
What juvenile arthritis is, signs to watch for in a child, the main types, why eye checks matter, and how a paediatric rheumatologist treats it.
Also known as: Childhood arthritis; JRA; Juvenile Rheumatoid Arthritis; Juvenile idiopathic arthritis; Still's Disease
What juvenile arthritis is
Juvenile arthritis is arthritis that begins before the age of 16. The most common form is juvenile idiopathic arthritis (JIA), once called juvenile rheumatoid arthritis. "Idiopathic" means the exact cause is not known. In JIA the immune system, which normally fights infection, mistakenly attacks the lining of the joints, causing inflammation, swelling, pain and stiffness that last for at least six weeks.
Many parents are surprised to learn that children can get arthritis at all. Juvenile arthritis is not the same as the wear-and-tear osteoarthritis of older age, and it is different from adult rheumatoid arthritis in several ways. With early diagnosis and modern treatment, most children with juvenile arthritis can go to school, play and lead active lives, and many go into long periods of remission. Without treatment, ongoing inflammation can damage joints, affect growth and, in some types, harm the eyes.
Symptoms
Young children often cannot describe joint pain, so parents may notice changes in how a child moves rather than complaints of pain:
- Joint swelling — a knee, ankle, wrist or finger that looks puffy or feels warm
- Joint pain, sometimes mild or not mentioned by the child
- Morning stiffness, or stiffness after a nap, that eases as the day goes on
- Limping, especially in the morning, or reluctance to walk, run, write or hold things
- A young child who goes back to wanting to be carried or crawling
- Fever that spikes daily, often with a faint pink rash, in the systemic type
- Tiredness, poor appetite and slowed growth
Some children develop inflammation of the eye, called uveitis. It often causes no redness or pain, so it can go unnoticed until vision is affected. This is why regular eye checks are part of care for many children with juvenile arthritis.
Types of juvenile idiopathic arthritis
- Oligoarticular — affects four or fewer joints, often a knee or ankle, and commonly starts in young girls. The risk of silent eye inflammation is higher in this type.
- Polyarticular — affects five or more joints, often small joints of the hands and feet as well as larger joints.
- Systemic (also called Still's disease) — daily high fevers, rash, enlarged glands, liver or spleen, as well as arthritis. It can occasionally cause a serious complication of excessive inflammation, so children need close follow-up.
- Enthesitis-related — affects the places where tendons attach to bone, such as the heel, and sometimes the lower back; more common in older boys.
- Psoriatic — arthritis with psoriasis or a family history of it, sometimes with swollen "sausage" fingers or toes; see psoriatic arthritis.
Causes
Juvenile arthritis is an autoimmune or auto-inflammatory condition. Researchers think it develops when a child with certain genes meets something in the environment, possibly an infection, that sets off the immune system. It is not caused by anything the parents did, by diet, by cold weather or by injury, and it is not contagious. It usually does not run strongly in families, although relatives sometimes have other autoimmune conditions.
How it is diagnosed
There is no single test for juvenile arthritis. The diagnosis is made by a doctor, ideally a paediatric rheumatologist, from the child's history and a careful examination of every joint, after ruling out other causes of joint pain and swelling. These include infection in a joint or bone, injury, reactive arthritis after an infection, rheumatic fever, blood disorders and, rarely, cancers such as leukaemia. Tests may include:
- Blood tests — blood count, markers of inflammation (ESR and CRP), and antibody tests such as ANA and rheumatoid factor that help classify the type and the eye risk. A normal blood test does not rule out juvenile arthritis.
- X-ray — to look for other causes and, later, for any joint damage or growth changes
- Ultrasound or MRI — to show inflammation inside a joint that is hard to examine
- Sampling of joint fluid if infection is suspected
- Eye examination by an ophthalmologist with a slit lamp, to look for uveitis
Treatment
The aim is to switch off the inflammation as early as possible, relieve pain, protect the joints and eyes, and help the child grow and live normally. Treatment is planned by a rheumatologist and adjusted over time.
- Anti-inflammatory medicines (NSAIDs) ease pain and stiffness, but on their own they rarely control the disease.
- Joint injections of a steroid into a swollen joint can settle inflammation quickly, especially when only a few joints are involved. Young children may be given sedation for this.
- Methotrexate, a disease-modifying medicine, is commonly used when several joints are involved or inflammation keeps returning. It needs regular blood tests to check for side effects.
- Biologic medicines are targeted treatments, given as injections or infusions, that block specific signals of the immune system. They are used when other treatment is not enough, and for systemic JIA.
- Steroid tablets are used for short periods in some situations, such as severe systemic disease, while other treatments start to work.
- Physiotherapy and occupational therapy keep joints moving, build muscle strength and help with daily tasks, writing and play.
Children on medicines that dampen the immune system need advice about infections and vaccinations; some live vaccines may need to be timed carefully. Ask your rheumatologist before any vaccine is given, and keep the record of vaccines on the immunisation schedule up to date.
Living with juvenile arthritis
- Keep all eye check-ups, even when the eyes look normal
- Encourage regular activity and play; swimming and cycling are often well tolerated
- A warm bath or shower in the morning can ease stiffness
- Talk to the school about extra time for writing, permission to move around, and support for sport and activities
- A balanced diet with enough calcium, protein and vitamin D supports bones and growth
- Support the child's emotional health; living with a long-term condition can be hard for children and parents
- Do not stop medicines when the child feels better without talking to the doctor, because flares are common after stopping too soon
When to see a doctor
See a doctor if a child has a swollen joint, a limp or morning stiffness that lasts more than a few days without an injury to explain it, or unexplained daily fevers with a rash or joint pain. Early referral to a rheumatologist gives the best chance of controlling the disease before damage occurs.
Call 112 or 108, or go to the nearest emergency department, if a child has a high fever with a hot, very painful joint and cannot move it or bear weight, which could be a joint infection; or if a child with systemic arthritis becomes very unwell, drowsy, has bleeding or bruising, or has a persistent high fever despite treatment.
Which doctor to see
A paediatrician often sees the child first. Juvenile arthritis is best managed by a rheumatologist, ideally one with training in children's rheumatology, working with an ophthalmologist for eye checks and a physiotherapist. An orthopaedic surgeon is rarely needed, but may help if joint damage occurs.

Common questions
Questions people ask
- Can children really get arthritis?
- Yes. Juvenile arthritis can start at any age in childhood, even in toddlers. It is an immune condition, not the wear and tear seen in older people. A child with a swollen joint or a limp that does not settle should be checked by a doctor.
- Will my child grow out of juvenile arthritis?
- Many children go into long remission, and some never have active disease again. Others continue to have flares into adult life. The course depends on the type, and early treatment improves the outlook. Regular follow-up is needed even when the arthritis is quiet.
- Why does my child need eye checks if the eyes look fine?
- Some types of juvenile arthritis can cause inflammation inside the eye without redness or pain. If missed, it can damage vision. Regular slit-lamp checks by an ophthalmologist catch it early, when treatment works well.
- Is methotrexate safe for children?
- Methotrexate is widely used in children with juvenile arthritis and is generally well tolerated at the doses used for arthritis, which are much lower than in cancer treatment. Regular blood tests check for side effects. Discuss any concerns with your rheumatologist.
This condition is usually assessed by a rheumatologist. Every profile shows the doctor’s registration and what has been checked.
