Still's Disease Symptoms

Fever

Fever is part of the body's own disease-fighting arsenal. Rising body temperatures apparently are capable of killing off many disease-producing organisms. For that reason, low fevers should normally go untreated. Although, if the fever is accompanied by any other troubling symptoms, you may need to see your doctor to be certain.

What is Still's disease?

Still's disease, a disorder featuring inflammation, is characterized by high spiking fevers, salmon-colored rash that comes and goes, and arthritis. Still's disease is also referred to as systemic-onset juvenile idiopathic arthritis. Still's disease was first described in children, but it is now known to occur, much less commonly, in adults (in whom it is referred to as adult-onset Still's disease or AOSD). Still's disease is named after the English physician Sir George F. Still (1861-1941).
