The Center for Disease Control and Prevention estimates more than
46 million adults in the United States (about 1 in 5) report doctor diagnosed arthritis.
Joint pain and progressive stiffness without noticeable swelling, chills, or fever during
normal activities probably indicate the gradual onset symptoms of osteoarthritis.
Painful swelling, inflammation, and stiffness in the fingers, arms, legs, and wrists
occurring in the same joints on both sides of the body, especially on awakening, may be signs of rheumatoid arthritis.
Fever, joint inflammation, tenderness, and sharp pain, sometimes accompanied by chills
and associated with an injury or another illness, may indicate infectious arthritis.
In children, intermittent fever, loss of appetite, weight loss, anemia or blotchy rash
on the arms and legs may signal juvenile rheumatoid arthritis.
