Treatment depends on the underlying cause of the red, swollen hands and feet. For Kawasaki Disease, intravenous immunoglobulin (IVIG) and aspirin are commonly used. Viral infections like HFMD typically require supportive care, including hydration and pain relief. Allergic reactions may be treated with antihistamines or corticosteroids. Infections like cellulitis require antibiotics, while JIA may be managed with nonsteroidal anti-inflammatory drugs (NSAIDs), disease-modifying antirheumatic drugs (DMARDs), or biologics.
