Still's disease is a rare form of inflammatory arthritis, characterized by systemic onset juvenile rheumatoid arthritis (SJRA). The disease is characterized by systemic inflammation, which affects the entire body. Symptoms of Still's disease vary depending on the individual, but generally include fever, rash, joint pain, and swelling.
Fever is one of the most common symptoms of Still's disease. These fevers typically occur in the evening or at night, and can last anywhere from a few hours to several days. The fever may be accompanied by chills and sweats.
Rash is also a common symptom of Still's disease. This rash is usually reddish in color, and can occur on the trunk, arms, and legs. It may itch, and may not always be present.
Joint pain and swelling are also common symptoms. The pain may be located in one or more joints, and may be accompanied by tenderness, stiffness, and/or warmth. The swelling may be mild or severe, and can occur in one or more joints.
Other symptoms of Still's disease can include fatigue, abdominal pain, muscle pain, and swollen lymph nodes. In some cases, people may also experience weight loss, enlarged liver or spleen, and chest pain.
It is important to note that the diagnosis of Still's disease is based on a combination of clinical features and laboratory tests. Diagnosis is usually made after other causes of the symptoms are ruled out. Treatment may include medications to reduce inflammation, physical therapy, and lifestyle modifications.
