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.

 OSTEOARTHRITIS

Joint pain and progressive stiffness without noticeable swelling, chills, or fever during normal activities probably indicate the gradual onset symptoms of osteoarthritis.

 RHEUMATOID ARTHRITIS

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.

 INFECTIOUS ARTHRITIS

Fever, joint inflammation, tenderness, and sharp pain, sometimes accompanied by chills and associated with an injury or another illness, may indicate infectious arthritis.

 RHEUMATOID ARTHRITIS

In children, intermittent fever, loss of appetite, weight loss, anemia or blotchy rash on the arms and legs may signal juvenile rheumatoid arthritis.
