Joint Pain in Children

Common Causes

• Juvenile idiopathic arthritis (JIA) — The immune system may mistakenly attack joints, leading to pain, swelling, and stiffness. It might affect knees or wrists in kids under 16 (Cleveland Clinic).
• Growing pains — Muscle aches in legs during growth spurts could feel like joint pain but are usually harmless and occur at night.
• Infections like septic arthritis — Bacteria might enter a joint through injury or illness, causing sudden pain and fever. Quick care is key (MedlinePlus).
• Lyme disease — A tick bite could lead to joint swelling and pain, especially in knees, if untreated.
