Six-year-old Sophia Samuel, a ray of sunshine in South Florida, faced a hidden battle. What began as a seemingly innocent fall transformed into a diagnosis of polyarticular juvenile idiopathic arthritis. Early mornings became a struggle to walk, leading to tests, X-rays, and a knee aspiration. But Sophia refused to be defined by her condition. With her family's unwavering support, she navigated treatment, embracing an active life. Even a recent setback with a hip hospitalization couldn't dim her spirit. Gymnastics, basketball, singing, and caring for her chickens filled her days. Sophia's resilience shone through, proving that arthritis wouldn't conquer her joy.
