Juvenile Arthritis (JIA)

Long-lasting joint inflammation that starts before age 16. Early care from a pediatric rheumatologist, regular eye checks and staying active help many children reach remission and live full, busy lives.

What is juvenile idiopathic arthritis?

Juvenile idiopathic arthritis (JIA) is the most common type of long-lasting arthritis in children. It begins before age 16, and “idiopathic” means its exact cause is unknown (NIAMS). In JIA the immune system becomes overactive and inflames the joints (NIAMS). It is not contagious, and there is no evidence that foods, toxins, allergies or a lack of vitamins cause it (Arthritis Foundation). You may also hear “juvenile arthritis” (JA) or the older name juvenile rheumatoid arthritis (JRA) (Arthritis Foundation).

About 220,000 U.S. children under 18 have arthritis of any kind (CDC), an estimate based on parents’ reports in a national survey from 2017–2021 (CDC MMWR). JIA is the most common form (CDC). Most types are more common in girls, and JIA affects children of every race and ethnic background (NIAMS).

The subtypes

  • Oligoarticular: four or fewer joints, often knees or ankles — the most common and mildest form, affecting about half of children with JIA in North America (NIAMS).
  • Polyarticular (rheumatoid factor negative or positive): five or more joints in the first six months. The RF-positive form tends to affect preteen and teenage girls and resembles adult rheumatoid arthritis (NIAMS).
  • Systemic: affects the whole body, typically starting with fever and rash; joints may become inflamed later or not at all (NIAMS). Roughly 10% to 20% of children with JIA have this type (Arthritis Foundation).
  • Enthesitis-related: arthritis plus inflammation where tendons and ligaments attach to bone, such as the heels and soles of the feet; more common in boys (NIAMS).
  • Psoriatic: arthritis with the skin condition psoriasis, sometimes with pitted nails or swollen “sausage” fingers or toes (NIAMS).
  • Undifferentiated: symptoms that fit no category, or more than one (NIAMS).

Signs to watch for

  • Joint pain, swelling, warmth and stiffness lasting at least six weeks, usually worse in the morning and after naps or long periods of sitting (NIAMS).
  • A morning limp can be one of the earliest signs — and younger children often don’t complain of pain (NIAMS).
  • Tiredness, rash, loss of appetite and fever (CDC). Systemic JIA usually causes daily evening fevers during flares; other types generally don’t cause fever (NIAMS).
  • Flares and remission: symptoms often come and go in cycles (NIAMS, CDC).
  • Growth: inflammation can make bones near an affected joint grow too fast or too slowly, causing unequal leg lengths or a small chin, and severe disease can slow overall growth. Growth usually improves once inflammation is controlled (NIAMS).

Diagnosis by a pediatric rheumatologist

No single test diagnoses JIA. Doctors suspect it when a child under 16 has joint pain, stiffness or swelling for at least six weeks, and they rule out other causes with a history, a careful examination, blood tests and sometimes X-rays, ultrasound or MRI (NIAMS). A pediatrician can make the diagnosis but should refer your child to a rheumatologist to confirm it and lead treatment (Arthritis Foundation); JIA is primarily treated by pediatric rheumatologists, working with therapists, eye doctors, nurses, social workers and mental health professionals (NIAMS). Seeing a doctor early matters, because delayed treatment can lead to joint damage and a weaker response to treatment (NIAMS).

The eyes: inflammation that can be silent

Uveitis — inflammation inside the eye — is common in JIA (NIAMS); an estimated 20% of children with JIA get it (Arthritis Foundation). The chronic form can cause mild symptoms or none at all, especially in young girls with oligoarticular JIA and a positive ANA blood test, yet untreated it can lead to cataracts, glaucoma and vision loss (NIAMS). That is why children with JIA need regular exams by an ophthalmologist (eye doctor) (NIAMS). For children at high risk, the ACR strongly recommends an eye screening every three months (ACR, 2026).

Get help fast for these.

There is reason for hope. There is no cure (CDC), but with treatment many children have symptom-free periods of remission, and some outgrow the disease and need no further medicine; for others it continues into adulthood (NIAMS). Controlling the disease early helps prevent permanent damage and improves quality of life (Arthritis Foundation).

Side by side

Six approaches compared

For every condition we look at the same six approaches: what each involves, what it typically costs, and what a patient can realistically expect.

ApproachWhat it involves Estimated costWhat to expect
Conventional medicine (AMA) Pediatric rheumatology care: NSAIDs and joint injections for symptoms; methotrexate and/or biologics to control the disease; physical and occupational therapy; regular eye screening; vaccines and infection precautions; growth and bone checks. Biologic cost estimate being researched — studies find medicines and visits drive most JIA costs. Physical therapy about $50–$350+ a session without insurance. School services are free under IDEA and Section 504; Medicaid covers medically necessary care for enrolled children. No cure, but early, strong treatment aims for remission, and many children get there. Some outgrow JIA; others need care into adulthood.
Chiropractic Not a treatment for JIA. We found no studies of chiropractic care in children with JIA. Not applicable. Safety of spinal manipulation in young children is not well studied. Talk with your rheumatologist first; avoid manipulating inflamed joints or the neck.
Acupuncture Gentle needling, alongside — never instead of — rheumatology care, if your child is comfortable with needles. About $125–$230 for a first visit and $90–$185 for follow-ups; community clinics about $50–$90. Very little JIA research: one 2025 trial found less pain and better function than sham acupuncture. Serious side effects in children appear rare.
Herbal medicine Not recommended to treat JIA. Supplements are poorly studied in children and may clash with methotrexate or biologics. Cost estimate being researched. The ACR advises against supplements or herbs to treat JIA. Always check with the rheumatologist and pharmacist first.
Massage therapy Gentle massage at home or by a therapist for comfort and relaxation, with your rheumatologist’s OK. About $60–$120 for 45–60 minutes with a private therapist, or $50–$90 at clinics and spas. Parent massage at home is free. One 1997 study found parent-given massage eased children’s anxiety and pain. Evidence is limited; massage doesn’t control inflammation.
MBHA Wellness Coach Family support: staying active and in sports, 504 plans and IEPs at school, fatigue, pain and sleep, emotional health, infection habits, the move to adult care, and JA camps and family groups. Cost estimate being researched. School plans are free; Arthritis Foundation JA camp is $25 (family camp $50). Supports — never replaces — your child’s rheumatology team.

Approach 1 of 6

Conventional medicine (AMA)

JIA care is led by a pediatric rheumatologist. Treatment aims to control inflammation, relieve pain, prevent joint and organ damage, and reach remission — little or no disease activity (NIAMS). U.S. care follows guidelines from the American College of Rheumatology (ACR). Its 2026 summary, approved in February 2026 with full papers still to come, promotes early and aggressive treatment, timely screening and shared decision-making with families (ACR, 2026, ACR). Much of the evidence is low or very low quality, so many recommendations are “conditional” (ACR, 2026). We name medicine classes only and never doses — your child’s team will tailor them.

1. Medicines

Most medicines need safety checks, such as regular blood tests for methotrexate (ACR, 2026). Taking medicines as prescribed is crucial to prevent permanent damage (Arthritis Foundation).

2. Physical and occupational therapy

The ACR suggests physical and occupational therapy, and physical activity, whatever medicines a child takes (ACR, 2026). Therapy aims to keep or improve range of motion, build strength and endurance, prevent injury and help children take part in daily life (ACR, 2021). Physical therapists build a home exercise program and help with sports safety; occupational therapists teach joint protection, pain management and energy conservation (NIAMS).

3. Eye screening

Eye exams look for uveitis and its complications; children who test positive for ANA need more frequent checks (NIAMS). The ACR strongly recommends screening every three months for children at high risk, and close monitoring for children who have uveitis, especially when their treatment changes (ACR, 2026). Ask your rheumatologist and eye doctor how often your child needs to be seen.

4. Vaccines and infection precautions

5. Growth, bones and the whole child

  • Growth usually catches up once inflammation is controlled (NIAMS). For children on long-term steroid tablets or infusions, the ACR strongly recommends checking height, weight and blood pressure at least twice a year, and bone and eye health at least yearly (ACR, 2026).
  • A healthy, age-appropriate diet — with attention to needs such as calcium — is encouraged (ACR, 2021).
  • The ACR suggests screening for mental health concerns and strongly recommends planning the transition to adult care (ACR, 2026). See the Wellness Coach section.

What it costs

What to expect

JIA may last a few months, a few years or a lifetime. With treatment, many children reach remission (NIAMS), though flares can still happen (Arthritis Foundation). Many children never need surgery (Arthritis Foundation).

Approach 2 of 6

Chiropractic

We found no studies of chiropractic care for children with JIA, and chiropractic does not treat the inflammation behind it. Neither the ACR’s 2026 guideline summary nor the Arthritis Foundation’s list of non-drug therapies for JIA includes it (ACR 2026 summary, Arthritis Foundation).

Safety

As a precaution, MBHA suggests that families talk with the rheumatologist before any hands-on spinal care, tell the practitioner about JIA and every medicine, and avoid manipulation of inflamed joints or the neck. For stiffness and movement, a physical therapist’s program has guideline support (ACR, 2026).

Approach 3 of 6

Acupuncture

Some families ask about acupuncture for JIA pain. The research is very limited.

What the research says

  • In a 2025 randomized trial of 106 children with JIA, eight weeks of electro-acupuncture improved pain and function scores more than sham (fake) acupuncture (trial, Clinical Rheumatology, 2025). It is a single study and needs to be repeated by others.
  • A UCLA pediatric pain specialist told the Arthritis Foundation she knew of no studies on acupuncture in children with arthritis — while noting that this doesn’t mean it doesn’t work (Arthritis Foundation).
  • Acupuncture does not replace medicines that control inflammation.

Safety

A 2026 review of pediatric acupuncture research from the past decade found no reports of serious side effects, though the data on side effects were incomplete (scoping review, 2026). Minor soreness or bruising can occur, and practitioners who treat children use fewer, thinner needles; a child’s comfort with needles is key (Arthritis Foundation). In the U.S., needles must be sterile and single-use, and most states license acupuncturists (NCCIH). Let your child’s rheumatologist know, so everyone is on the same page (Arthritis Foundation).

What it costs

Published examples run about $125–$230 for a first private visit and $90–$185 for follow-ups; community clinics about $50–$90 a visit. Insurance coverage varies (The Pricer).

Approach 4 of 6

Herbal medicine

No herb or supplement has been shown to treat JIA. The ACR recommends against using supplements or herbal products specifically to treat JIA: its panel was concerned about the safety of unregulated products, and there are only very limited data in children (ACR, 2021, ACR, 2026). It also strongly recommends against relying on a special diet alone; overly restrictive diets, such as gluten-free or dairy-free, can leave nutritional gaps (ACR, 2021).

Why caution matters

  • Many supplements have never been tested in children; “natural” doesn’t always mean safe; supplements can interact with medicines; and labels don’t always match what’s in the bottle (NCCIH).
  • Cat’s claw might make the immune system more active, and Asian ginseng may worsen autoimmune disorders; some experts advise against ginseng for children (NCCIH).
  • For methotrexate, families are asked to tell the doctor and pharmacist about all vitamins, supplements and herbal products; the doctor usually prescribes folic acid alongside it (MedlinePlus). Don’t add vitamins on your own.

Before giving any supplement, show it to your child’s rheumatologist and pharmacist — especially with methotrexate, a biologic or steroids. Never stop or change a prescribed medicine on your own (Arthritis Foundation). We don’t list doses here.

Approach 5 of 6

Massage therapy

Massage won’t control the inflammation of JIA, but some families find it soothing for sore, stiff muscles and for stress. The Arthritis Foundation lists massage among non-drug therapies (Arthritis Foundation).

What the research says

  • In a 1997 study of children with mild to moderate juvenile arthritis, parents gave a 15-minute massage every day for a month while a comparison group did relaxation therapy. Massage immediately lowered anxiety and a stress hormone, and over the month pain fell on children’s, parents’ and doctors’ reports (Field et al., J Pediatr Psychol, 1997).
  • A newer pilot trial of massage for JIA pain was stopped early because it couldn’t recruit enough children (ClinicalTrials.gov), so the evidence remains thin.

Safety

Massage is generally low-risk, but rare serious problems, such as a broken bone, have been reported, sometimes with vigorous or deep-tissue work. Don’t use massage to put off seeing a doctor (NCCIH). MBHA suggests gentle pressure only, no pressing on hot or swollen joints, and asking the rheumatologist or physical therapist to show you safe home techniques.

What it costs

About $60–$120 for 45–60 minutes with a private therapist, or $50–$90 at clinics, gyms and spas (CostHelper). A parent’s gentle massage at home costs nothing.

MBHA Wellness Coach

JIA touches the whole family. An MBHA Wellness Coach can help with the everyday side of living with it — alongside, never instead of, your child’s rheumatology team.

Staying active and playing sports

Children with JIA can play sports: staying active builds stronger muscles and bones and supports emotional well-being. They may need to skip some sports during flares, and once JIA is controlled most sports are fine with the doctor’s OK (Arthritis Foundation). Swimming, water exercise, cycling, tai chi and yoga are good choices (CDC). Rest more during flares, exercise more when symptoms are quiet, and prefer short breaks to long bed rest (NIAMS).

School: 504 plans and IEPs

Fatigue, pain and sleep

Tiredness is common (CDC). Help your child learn self-care: take medicines as prescribed, get enough restful sleep, exercise and pace themselves, eat a balanced diet, and reduce stress with deep breathing and supportive friends and family (Arthritis Foundation). Occupational therapists teach energy-saving and pain-management skills (NIAMS).

Emotional health

Young people with long-term conditions are at greater risk of anxiety and depression. Relaxation, physical activity, support groups and mental health professionals can help (NIAMS), and the ACR suggests mental health screening whenever possible (ACR, 2026).

Everyday infection habits

Good hygiene and frequent hand-washing are the most important things children can do to prevent infection (Arthritis Foundation). Keep the family’s vaccines, including yearly flu shots, up to date (ACR, 2021).

Growing up: the move to adult care

Some children’s arthritis improves as they grow; others continue to have symptoms as adults, and moving from child to adult care can be hard (CDC). The ACR strongly recommends checking readiness and making a transition plan (ACR, 2026). A coach can help teens learn to manage their own appointments, medicines and questions.

Camps and family organizations

  • Arthritis Foundation JA camps are for children 8–17 with juvenile arthritis or a related childhood rheumatic disease, supervised on site by health care professionals. Resident camp costs $25 and family camp $50 for up to four people; registration runs December through March (Arthritis Foundation).
  • The Arthritis Foundation helpline (1-800-283-7800) and its juvenile arthritis resources can connect families with information and support (Arthritis Foundation).
