The early signs of Still's disease, also known as systemic juvenile idiopathic arthritis (SJIA), are often non-specific and can vary in severity. Symptoms may include joint pain and swelling, especially in the knees, elbows, and ankles, as well as fever that lasts for more than three days and is accompanied by a characteristic salmon-pink rash. Other early signs may include fatigue, loss of appetite, and weight loss.
Joint pain and swelling is typically the first symptom of Still's disease. It is often accompanied by a low-grade fever, which may come and go for a period of weeks or even months. The joint pain can be quite severe and can limit range of motion, making it difficult to move the affected joint. Swelling is usually visible and is most noticeable around the joints.
The characteristic salmon-pink rash of Still's disease may develop soon after the fever and can last for several days. The rash may be accompanied by itching and is often worse at night or after exercise.
Other early signs of Still's disease include fatigue, loss of appetite, and weight loss. These symptoms can be subtle and may be difficult to distinguish from the normal fatigue and appetite changes associated with childhood growth and development. If any of these symptoms persist, it is important to seek medical evaluation.
Early diagnosis and treatment of Still's disease is important to prevent long-term damage to the joints. If you or your child is experiencing any of these signs or symptoms, it is important to speak to your doctor for further evaluation.
